when two really gay guys shove a tube in their asses and make a poor lil hamster run through it. between their asses. so the hamster can anally rape them.
Gay dude #1: Wanna do some hamster racing?
Gay dude #2: I've got the hamster if you got the tube.

Get the hamster racing mug.
When a male proceeds to ejaculate on a women's anus and the cum rolls down towards the genitalia. The cum resembles a Russian hamster racing.
"BRO GUESS WHAT!?"

"What?"

"Last night my Russian Hamster raced to her Vag in 6 seconds!!!!"

"No way, NICE!"
