size play 

Sexual intercourse with much larger or smaller partner(s).

I'm into size play, so I hired seven midget manwhores and got them to dress up as dwarfs.

Size Queen Radar 

when a knowledgeable fan of big cocks can easily spot a guy sporting impressive meat.

Travis noticed a lanky guy walking down the street and used his trusty Size Queen Radar to determine that yes that dude was hung like a rhino.

size dropper

A poop so large that it, upon completion, enables the dumper to drop down a waist size and/or a notch in their belt.

I feel especially light on my feet after that size dropper I left back in your bathroom. I'm a 31 waist for at least the next few hours.

Size Denial 

Either one of two things:

1.(n.) When a person (usually overweight) can no longer fit into clothes of a particular size but continue to buy and wear clothes of said size, despite what their gut/hips might have to say about it. Typically occurs when a person refuses to accept that they've either become fat, or(in the case of an already lardy person), have gained even more weight.

2.(n, abstract) When a person who may feel a touch insecure about the size of their..."thing " buys condoms larger then they are.
This often leads to slippage.

1. Suffering from a classic case of size denial, Jack continued to wear his favorite size 30 jeans, despite the fact that his waistline bordered size 38.
(please note that this phenomenon is more prevalent in women.)

2. Luke wanted to buy condoms, but he when he found out he was "Garden Snake" size, his size denial kicked in.
So instead, he grabbed the Anaconda ones instead.

Size up 

The phrase "size up", usually used in arguments, essentially means to "stand up and fight"

"Yo, no long talkin' b. Either size up or nize up"

In other words...

"Hey man, I don't want to do this long talking business anymore. Either stand up to me and let's fight, or shut up."

size queen 

Uh, lets be clear about this. The whole "queen" lingo lexicon was created in the gay community. A size queen is a dude who digs the massively huge penis, forsaking all others. Any reference to a woman being a size queen is great, but a secondary definition.

Dennis has a small pee-pee and Bruce, the size queen she is, would never put up with that shit.
