'Nooo...thats just how i normally act. u could definately tell if i was actually flirting with him.'
1. To intentionally behave in a way that one believes will induce sexual arousal in their target. This word is distinct from 'tease' in two respects - firstly, it doesn't imply that the subject does not intend to satisfy the sexual arousal that he or she has manufactured and secondly, whereas the verb 'to tease' is usually used in reference to a woman's actions, the verb 'to flirt' can be used in reference to a man or a woman's actions.
2. To toy with (an idea usually, but sometimes an entity.)
One who is known to indulge in the actions detailed in the first verb definition can be described as 'a flirt'.
1. He flirted with me all night, with his characteristic double entendres, his charming smile and hypnotic eyes a-glow.
2. She flirted with the idea of joining the Communist Party, but eventually decided to stick with Labour.
She wins the attention of all the men - she is a flirt out of the top drawer.
