The act of holding in urine for long periods of time, causing the bladder to expand and push on a persons diaphragm. This causes the cocker to feel/look two months pregnant. This is not a dirty word, although commonly confused for one by its name.
While i was scoring, the extremely attractive girl I was with was afraid to use the portable toilet and therefore decided to cock.
I was cocking at the very close game of rugby.
Don't you hate the feeling when your bladder is cocked?
