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..."

train boy

A train boy is someone who thinks that Dodge from "Locke & Key" is unbearable for throwing a kid in front of a train, regardless of that scene's ties to the comics. And they will do anything to reinterpret the rightful owner of the eponymous magical keys as someone evil enough to shame Lord Sauron and despicable enough to make Dolores Umbridge tremble, no matter how many times she reminds us the keys are her property before Bode found them, or saves Kinsey from drowning, or saves Tyler and Nina from Sam. And they will compare any strong female character to her and say that we're "the definition of delusional" for disagreeing. A common argument from a train boy is that killing a kid automatically makes someone "objectively evil" for the rest of their lives but also that Sam setting dozens of underage prisoners on fire doesn't stop him from being "a good guy". Train boys may call us Satanists before reveling in Sam's nihilistic nature, or call us simps before simping over Eden or Jackie. Overall they base their tastes (or lack thereof) around girls badass enough to utilize trains as killing tools, and those too weak to try.

"I think Dodge is a wonderful person and iconic character"
"Haha silly fanboy, you're just jealous of how attractive and cool Jackie and Bode are"
"Okay train boy"
