When a guy cums in a girls mouth and she acts like she's swallowed it and goes in for a kiss. During this she will spit the semen into the guys mouth (like a bird feeds it's young) forcing him to taste his own cum. Once he realizes it's his own cum he will gag and throw up while the girl laughs.
Dude, last night she was backwards bird feeding me. I haven't eaten all day...
