doo-doo stains 

A doo-doo stain is the result of improper wiping after taking a dump. After taking the dump, when you pull your pants up.. your poop may go through your underwear and straight onto your pants/shorts/dress/shirt or whateverthefrik. You'll be humiliated in public and bye bye reputation :)

Make sure you wipe that butt kids!!

Damp Stains

The name of an up-and-coming Westerly, RI boy band. A wet spot left on a female's panties after seeing one of these members.

The Damp Stains were in town and all the ladies that came to see them left with damp stains in their panties.
Songs off of the debut album include:
Love & Loafs
I can still smell you love on my finger(s)
Losing the Biscuit Game
The Shocker
Don't use your teeth
That was our sweaty bodies rubbing together, not a fart.

Camping Stains 

Non-descript stain (and/or stains) on tents, sleeping bags, tables, portable grill, pillows, blankets, shoes, chairs, picnic tables, socks, under garments, air mattress, all of the above, but mostly shirts that which you have no recollection as of how they got there after a night and/or weekend of camping combined with power drinking.

Dude, what the hell is that all over your gear?

Hmm? Oh shit, I dunno. Camping stains?
