Uni-boob 

The awkward lump formed by a zippered sweatshirt when you sit down. Categorized as a uni-boob when the lump is at your breast area. Can also be at crotch area forming a regular boner on a male and a lady boner on a female. Also a stomach boner when the lump is at your stomach. Obviously. So much "excitement"...

"Stupid sweatshirt is giving me a stomach boner!"

"If you unzip it halfway then it'll go away."

"Well now I have a lady boner."

"Better than a uni-boob!"

uni boob 

One boob that extends the same distance as if you had 2 boobs. its quite unfortunate and can often happen when so much fat has extended across the barrier from one breast to the other, forming a uni boob.

"yo dude! man your boobs arent individual any more"
"i know dude, coz i totally got uni boob. its the new fashion"
"i should get me one of those"
