When you place an open can (coke, Dr. Pepper, monster, beer, etc.) in someone’s asshole, stab a hole in the bottom once placed, and shotgun the said substance.

Breaking wind while performing a blow job
Dammit, I was sucking on a huge new cock last night. Everything was perfect, except I was a little bit drunk, and I broke wind right in the middle of it all. Thank god he was drunk too, and we made a joke and called it mufflered fellatio. We had great sex, but I was pretty embarrassed.
