On the topic of porcupines, I found some thing interesting and a little amusing.

The urban slang for the word.....

porcupine
A woman that has really been around

comes from the phrase "if she had as many dicks on her as shes had in her she'd look like a porcupine"
damn dude u fucked mary too so did greg ,john, curtis, and about 15 other guys before them

yea that bitch is a porcupine for sure
