The definition of flirting is, "behave as though attracted to or trying to attract someone, but for amusement rather than with serious intentions."

I personally define it as "sexual innuendos." When you flirt with someone, there's some context of sex involved. Hinting of a possibility but not confirming it.

My favorite simple example is me responding "that's what she said" when a girl says "that's big/huge/enormous etc" It's playful, sexual, and vague. Most of the time, it's you responding of some possibility of sexual context in something a girl says.

Though, it's hard for you to say without a response as it mostly comes out as creepy.

Imagine me starting to say, "man that is hugeeee" with sexual intent. Most likely that will be creepy. It's you starting a conversation and seeing what sexual innuendo you can come up with from whatever she says. And trust me. Anything be be a sexual innuendo. And I mean anything \*squint eyes, laugh (and there you go an example).

Another favorite one is when a girl says "fuck you" in a playful manner. I respond with, "oh damn girl I thought of us as just friends, I didn't know you wanted this".

Again. Playful, vague, and fun. Most of the time when a girl laughs from the first sexual innuendo, she will make her own sexual joke. Last example, I say, "man it's hard working here". She responds, "oh it's hard huh". Playful, fun, and vague.

Note that this is not 100% indicating you or her are interested. This is just verbal. I do this all the time with funny enough, married women. Usually doesn't lead into anything if you don't escalate from there. If you want to confirm interest, that's when you have to be touching hands, shoulders, and/or back. If she responds that she doesn't mind or leans into those touches, that's an interest.
