An anal blowfish occurs by putting your gasey partner on all fours, begin tonguing the anus until your partner farts into your mouth causing a firm puffing of the mouth cheeks - resulting in an anal blowfish.
My partner and I enjoyed anal blowfish last night!

When one person moons another through a glass window but puts their anus against the glass and farts. Similar to a blowfish but using the anus instead of the mouth.
