its your birthday

Used by rappers and dorky white kids, its your birthday means that you have completed something and your friends (if you have any) and proud of you, resulting in them saying "its your birthday" meaning "Congrats! You've done some ordinary thing that many other people do, but I'm going to use the phrase "its your birthday" to sound cool, and hip, because I saw it on MTV!!!!"
Yeah.

White Guy 1: Oh my golly, I do believe its your birthday, gee, go you!
White Guy 2: Aw, shucks thanks, teehee.

it's your birthday

A term of encouragement often used to drunkenly encourage equally intoxicated acquaintances. Rarely used on the subject of encouragement's actual birthdate. Commonly preceeded by "Go (name)" and occasionally followed by, "no it's not, go anyway" when spoken by those in the 8-13 year old age bracket (who are hopefully not drunk).

"Look, Susan's about to dance on the bar!"

"Go Susan, it's your birthday!"
