After your partner is done giving you a blow job, she proceeds to turn around and fart/queefe on the head of your penis (the part that looks like a mushroom)
After Bradley was done fingering Bisbee's butthole, Bisbee sucked his cock and farted on it, and bradley said "thank you for the burnt mushroom!"
Similar to overcooking a bag of microwave popcorn; it's a fart that smells so bad that there is no way you can hide it. It fills a room and never seems to go away.
When a girl is giving a man a blow job and resist to let him cum in her mouth.He quickly smacks her across the face with a burnt salmon knocking her out...then he finishes the job in her mouth
Heather was afraid of getting jizzed on so Jon gave her the burntsalmon
Left over sperm or semen in someones asshole from a prior fuck that is re-fucked by another dick and thus becomes overheated and burnt. It's odor is that of burning flesh and feces put together.
Bob: This girl, Kim Cumbox, farted on me while we were fucking and it smelled horrible!
Fred: Haaa! You fucked her!!?? That ass is FULL of Burnt Sperm! You better take a shower!
