Lean into body language.
Beyond showing off your pearly whites, body language goes a long way when flirting. Murray suggests “leaning towards them with your body” and “having your feet face them so you are looking at them.” It's an easy way to signal openness and let the other person know you're interested.
Keep your body language open and relaxed. The key to good flirting often comes down to how you present yourself. Stand or sit with your shoulders back and your arms at your sides (or, at least, not across your chest). Do your best to look friendly and open, and offer a genuine smile when you're flirting.
Things You Should Know
She's definitely flirting if she looks at you frequently, teases you, touches you when she's excited or happy, or texts you random, funny things. She might be flirting if she laughs at your stories, calls you nicknames, makes up excuses to talk to you, or adjusts her body language toward you.
Clues to spot flirting are body language, such as smiling, leaning forward, and touching, and verbal cues such as compliments or references to being available. You can also ask yourself if the person's behavior is consistent over time and whether they act differently with you than they do with others.
In his book he examines five key styles: polite, playful, sincere, and traditional. Take the quiz here to see which one you are. There is no right or wrong way to flirt, but according to author Jeffrey Hall there are five different styles.
A person will flirt with another by speaking or behaving in such a way that suggests their desire to increase intimacy in their current relationship with that person. The approach may include communicating a sense of playfulness, irony, or by using double entendres.
Women take a passive role, receiving attentions warmly but without taking on any risk of rejection or making a bad impression. Their flirting is limited to indulgences like prolonged eye-contact, and "other nonverbal behaviours" (think twirling your hair and pretending to laugh).
Make your best impression.
A flirty smile uses your eyes, your head, your neck and even your whole body. There are different flirty smiles, small little smirk, one side of your lip raising just a bit, the closed mouth raised eyebrow, or even biting your bottom lip gently.
Intense eye contact, especially with a smile, may mean the person has a crush on you. Pupil size increases means the person likes what he/she sees. Glistening eyes can signify strong attraction and perhaps even love.
The eyes 👀
It's true: Your eyes really say so much. I like to use the eyes emoji when I'm feeling bold and most often when I'm swiping up on a hottie's thirst trap Instagram selfie.
Touching becomes flirting when it's done in a playful or affectionate manner. This could include a light touch on the arm during a joke, a playful nudge during a game, or a gentle touch on the hand while sharing a moment. The key here is that the touch is not aggressive or intrusive, but gentle and affectionate.
Giving compliments, using suggestive body language, maintaining eye contact, and perking up when you are around this person are all subtle signs of flirting.
Physical
Physical flirts are big on touching. They'll lean into you, adjust their stance toward you, play with their hair or put focus on their mouth—this style of flirting is sexually charged, to say the least.
During the flirting stage, a guy who likes you will attempt to show you his best sides. He'll talk about his new apartment, his band, his promotion, or his talents. Some men may even shower you with expensive gifts, invite you to watch them play a sport, or make an extra effort to improve their physical appearance.
Men who are attracted to you might even engage in more touch. If a man actively tries to touch you during your interaction, it may mean he wants to get closer to you or close the distance between you two.
In a nutshell, you want to try to touch the other person 5 times within 15 minutes. You can naturally touch someone while joking around (coming next!), when you meet someone, and even when making eye contact for even more flirting power. For intimate touches, try touching closer to the 3 Hs: Hands.
Tease your crush just a little bit.
Tease them gently about something they're good at/confident about. If your crush is a star athlete, try saying, "So how many extra goals is your team going to score when they don't have you on the field?"
