trampoline sponge cow

when you walk in on your fat parents having sex and they both look at you without stopping, smile at you, and then continue to cause creaking that can be heard throughout the whole neighborhood. You are traumatized for life. Your childhood is over because of what you've just seen.

"hey what's up" "don't talk to me. I experienced trampoline sponge cow last night" "oh gosh man I'm so sorry."

Stretching out your scrotum and placing a Mexican jumping bean on it. The bean will bounce up and down off your scrotum like a trampoline.

I paid some homeless dude in Guadalajara 20 pesos to show me a Tiajuana Trampoline.
