I have been trying to make a list like this for a while, basically a list of what smells characters use to describe stink bombs.
However, not all character quotes about stink bombs describe a smell. For example, Wade's comment "Awww, stink bombs rock!" doesn't count. But, the quote by Troy, "I must have farted or something..." means that he thinks it smells like his own fart. This is sort of like a scavenger hunt for stink bomb quotes.
Troy: smells like his own farts.
Trent: stinks like your mom.
Peanut: smells like the boy's locker room after basketball.
Ricky: smells like Edna's breath
Damon: smells like a hotdog full of dog crap with baby diaper.
Officer Monson: smells like cigarettes and ball fungus. (yeah, I cringe at that one)
