look up any word, like bangarang:
 
1.
When someone kicks you in the crotch so hard that your dick swells into the size of an apple.
Person 1: OMG I can't believe she kicked him in the nuts so hard!

Person 2: Yeah he's totally got applepants.

2.
Apple Pants; When a female is on her period and the flow is heavy enough to soak through the front of her pants, skirt or underwear and look a bit like a red, shiny apple.
I saw Brittany today, she didn't know it but she had apple pants.
