when a girl gives a guy head while she is pissing.
I gave Tyler a BIRDJOB while I was pissing on New Year's Eve.

A bird Job is when you cum into someones mouth, they swallow it and then regurgitate the semen back up. Then the person who came licks the vomited cum out of the others mouth. The same way as a bird feeds its babies.
Dude! you like bird job's? That makes you a manrantula!
