When a shemale fucks you in the ass through a rip in your pants, resembling a walrus' teeth. This is called a Japanese Walrus Sandwich, which is recommended never to try.
OMG! I just saw this porn and the shemale gave him a Japanese Walrus Sandwich!

Myles: Oh, Ryan gave him a Japanese Walrus Sandwich.
