Trainbow

The train that rides the rainbow, allowing to move at light speed but at the same time bring joy to the hearts of all children.

"Whoa, did you see that Trainbow?"

"Yeah it totally just targeted some starving third world country children!"

Trainbow

Trainbow. A bunch a homosexuals runnin a train on each other. Most likely anal. Definitely butt stuff.

Hey guys, it's Bruno Mars! I bet he would love a to be on the rails when this trainbow comes steaming through his back yard.

Mitch wants to do buttstuff, so Mitch volunteered to be the caboose when his buddies invited him over for a good ol Trainbow.

Trainbomb

It's a term used in Miami Florida
It's meaning stems from the word "Train", performing group sex on one female who is willing.
Usually men find a girl who is fucked up enough or down to fuck. Some guys fuck a girl in the dark then
call other guys to come through and fuck their girl when they are bored and thats how some trains start.

Jimmy is fucking lisa in his room, "Lisa, I'm getting tired, lets take a break", "No Jimmy, I haven't gotten off I need to have at least 10 orgasms before we can stop". Jimmy looks at Lisa sideways, while still fucking her he picks up his phone in one motion. "I am going to call my friend Luis so he can help me out" Jimmy calls Luis, "Yo luis, my girl Lisa wants 10 orgasms and I can't fucking do that, you wanna call a couple homies to come trainbomb this bitch"...."Jimmy, I'm so excited..."
