What is It's My Birthday?
1.
An expression of delight, accompanied by dancing around. Basically saying that the person in question is great, skilled, lucky, etc.
Ususally said in a kind of sing-song way.
"Ooooh yeah! I just won that race! It's my birthday! It's my birthday!"
2.
Used by either sex to trick the other party, (usually in a bar)into purchasing you a drink, or perhaps used to elicit some kind of sexual favor later on in the evening.
"How's it going? It's my Birthday tonight!! Oh you wanna buy me a shot?!"
