A Dirty Bullfrog is when you stretch your scrotum back over your anus, and then fart. The resulting skin-balloon and muffled noise looks and sounds exactly like a bullfrog.
My girlfriend was giving me head last night, and I had to fart. I didn’t want her to stop, but I didn’t want to fart in her face, so I pulled the old Dirty Bullfrog.
