This one is sung when somone is forced to drink at a social.  This can be caused by several things, the two most common being:
1) He scored his first try and is shooting the boot
2) He fucked up a line in a song, and now has to redeem himself 

Why was he born so beautiful
Why was he born at all
He's no fucking use to anyone
He's no fucking use at all
 
He should be publicly pissed on,
He should be publicly shot (bang, bang),
He should be tied to a urinal,
And left there to fester and rot.
 
So, DRINK MOTHER-FUCKER DRINK MOTHER-FUCKER DRINK, DRINK MOTHER-FUCKER DRINK MOTHER-FUCKER DRINK...........
Continue this harassment until the dumb-ass finishes his beer!
