Frosted Walrus
When a bitch is giving you head, as you blow your load in her mouth, you pull her hair back and karate chop her throat... Causing your cum to shoot out her nostrils and hang down like walrus tusks, hence the term frosted walrus.
I heard that bitch is down with the frosted walrus.
Frosting Walrus
A sexual act where, as one ejaculates in a mouth, they then punch their partner in the stomach, forcing jizz to shoot out the persons nose.
DUDE!!! I CAN'T BELIVE YOU GAVE THAT GIRL A FROSTING WALRUS LAST NIGHT...WHAT THE BEAN!
