The term 'white cap' is used to describe a member of a group of try-hard teenagers who dress similarly; particularly by wearing a white baseball cap. The cap can be any brand as long as it is white all over and is worn with two special adjustments: having the hat sitting as far back on your head so that your fringe is visible and sticking out at the front and leaving the hat adjustment tag dangling down your neck. Most white caps also wear XXXXL nylon track pants (usually Kappa brand) and XXXXXL shirts (preferably polo). Lastly, white caps usually wear Nike sneakers (or similar), presumably because they need to run from the police so often after tagging public property. According to white cap mentality, tagging a wall is a form of art and makes them ghetto. Apart from their similar dress sense white caps or 'lads' (as they refer to themselves as) are troublesome individuals who are even worse when combined in a group. Their saturday nights usually invovle going to parties they are not invited to and gate crashing. After being kicked out by bouncers and causing a huge commotion (often resulting in brawls), lads then roam the streets looking for people that are smaller than them or alone to beat up or roll. However, most 'white caps' are scrawny and weak, with little to no muscle tone, so often this hunt for smaller people can take a while.
Average Person: "What did you do last night?"
White Cap: "Oh man we tried to gate crash this party then this 'seca' stood on my mates brand new Nike's so we dropped him!"
Average Person: "Hold up, whats a 'seca'?"
White Cap: "Security guard bro"
Average Person: "Why don't you just call them security guards?"
White Cap: "Yeah ok, you go ahead and waste your life calling them that. Want a durry?"

When Ronny hadn't seen Ben for two months, and then saw him hanging in a seedy back alley smoking, with his new Kappa pants dragging on the ground, and an XXXXXL polo shirt which looked like a skirt, and a hat which was worn at such a precarious angle it made him look like he was wearing one of those jewish skull-cap thingys, he knew Ben had become a white cap.

A small remnant of white toilet paper clinging near a girls butthole, that a man discovers while doing a girl doggy style and gets ambitious spreading her butt cheeks. Usually specific to a girl with large cheeks that ripple and wave like an ocean while she gets smacked from behind. A skinny girl with pancake ass more accurately has a dingleberry as opposed to a white cap.
Man, I was hitting that girl from the gym with the huge cakes from the back the other night... when I cracked open those cheeks I spotted a white cap and had to close it back up real quick before I went into Boner Shock.

An erupting zit, usually near your mouth, that is painful and soo terribly obvious to everyone else because the entire top half of it is white with puss. Usually once popped it pusses back up two or three more times and also bleeds like a bitch every time it is popped.
Damnit there is no way I'm getting any ass tonight with a white cap like this on my lip!

When a male ejaculates and either places a tissue or white crew sock over his penis to absorb the semen.
White Capping; Wow, I have to clean up this mess before my mother comes in and finds it. Find me a tissue or a sock so I may place this white cap over my dick.
