Based on the battle record of the evil Decepticon leader from 'Transformers', Megatron means to wreak havoc when able, but to turn tail and bitch out at the first sign of adversity.

A penis that exhibits the "grower" characteristic of significantly expanding and lengthening upon erection as opposed to the "shower" characteristic where it is already near maximum size at rest and does not get much bigger upon erection.

Anal penetration, with no warning, no luracation, or condom.

origin; Holyoke Ma.

Something that is huge or really big, usually used as if something is really bad (because Megatron is the bad guy in Transformers)

Starscream’s Bitch

Song by Nicki Minaj

Brra, ta, ta, tat
Brra, ta, ta, tat
They call me Megatron

Just did a telethon
He got Margiela's on, and I get my jealous on
I fuck him like I miss him
He-he just came out of prison
Bitches-bitches be talkin' shit, but they ain't got a pot to piss in
My-my name is Nicki M
I'm in a sticky Benz
That-that mean it's candy apple red, I'm Barbie, this is Ken
That is a Fendi fact
I'm with a hundred Macs
Oh, this is custom made, Donatella sent me that
Feel up, baby, feel on me
Pull up if you're feeling lonely
Feel up, baby, feel on me
Pull up if you're feeling lonely
Brra, ta, ta, tat
Shots, shots, shots, I'm drinkin'
It's better when I'm drinkin'
I tune up when I'm drinkin'
Rum, rum when I'm
Brra, ta, ta, tat
Shots, shots, shots, I'm drinkin'
It's better when I'm drinkin'
I tune up when I'm drinkin'
Rum, rum when I'm
Brra, ta, ta, tat
Brra, ta, ta, tat
Brra, ta, ta, tat
They call me

Shorty's a mega con
It ain't about the race either, it's a marathon
I put the squeeze on him
Throw up the B's on him
That ass clappin' on the D, Hercules on him

My name is Baddie, Baddie
I keep it tight for zaddy
He keep it comin', comin', he ain't he even drop the addy
Trunk in the front-front
I need a blunt-blunt
I own my own Moscato, bitch, we gettin drunk-drunk
