Penis

The penis is a male body part in-between your legs, some call it a muscle and some call it a bone. There are a thousand different slang named for the Penis, but I can't list them all. It is used to reproduce and create new life, however, some use the penis to masturbate or pleasure themselves or other individuals. It is also considered a "Private Part" Meaning you should not expose it to anybody without their consent!

guy: "Im a boy, so I have a penis"
girl: "Good for you mate"

t-erect

When a dude gets so turned on his penis grows so large it looks like a dinosaur penis.

Emma: "Watching porn by yourself dude?"
Dude: *Gets extremely turned on*
Emma: "Woah, hey there mr. T-erect

Piss Leakage

When there are two streams off piss coming out of your penis and it gets everywhere and all over your clothes, the floor and the ceiling, basically all over your bathroom. (Sometimes also you can try to control it but it is VERY hard to do, and you will probably end up making the situation worse)

Person 1: "I Had a piss leakage today.."
Person 2: "oh man that sucks!"

Dominant Shit

When you are on the toilet taking a fat poop and your entire body except for your anus becomes extremely weak, the poop coming out of your anus is absorbing the muscles of your body because you keep pushing it out so hard, and then after taking a dominant shit, you are left there for like 6 minutes with a weakened body just questioning wtf happened.

guy 1: "I'm pooping"
guy 2: "Good for you I guess"
guy 1: "Fuck im taking a dominant shit"
guy 2: "Dude call 911!"

Sentient piss

When you are taking a piss and then the piss gains conscious and gains a mind of its own and decides to go every single area possible, and it goes all over the walls, floor and ceiling, leaving you to stand there steaming mad while absolutely drenched in piss.

Guy 1: "Im gonna take a piss"
Guy 2: "ok I don't care"
Guy 1: *Takes a sentient piss on accident*
Guy 1: "Well that is shit! I had a sentient piss!"
Guy 2: "Oh man I hate when that happens"
