Referring to the S on Superman's chest. When someone walks around like they got a s on their chest, they walk around like nothing can harm them or like they're invincible or something.

an insecure asshole who walks around in a superman tee shirt, tattoo, necklace etc. trying to show people he's tough...
I know you're like me, when you see someone walking down the street in a Superman tee shirt, you just want to shoot them in the chest. And when they start to bleed go, "I guess not." Don't wear the shirt. Wear a shirt that says, "I bleed if you shoot me in the chest plate" and I will not shoot you in the chest plate, Superbleeder. Haha I called him Superbleeder.

I think i need a bigger s on my chest.

To feel superhuman, like how superman has an "S" on his chest.
You were there like a punk,
Just to get in my face,
Wanted in me wanted to be
Till I gave you a taste
Don't need your goddamn pressure
Frontin' stress I'm superman motherfucker
Without the s on my chest
Trying to step in my circle I'm leaving you purple and black
On your back drop your ass like a heart attack
Rippin' through your life like a motherfuckin'
Hurricane fist full of Novocain for the pain

Commonly mistaken for being invinceable like "Super Man".
There is nothing super about s on my chest. Actual use is as a descriptive term for ladies who have been Skeet on or in laymans terms cum on.
Gurrl, did you have fun at Hobo Scratch's Crib?

Shit yo, yous a triflin bitch!
