The act of sitting on a toilet backwards, so your knees touch the wall behind the toilet, and pushing excrement through the anus, so that it spills down the front of the bowl and stains it really badly.
John: For fuck's sake, Mark, I can't go into that toilet.
Mark: Why, John?
John: Some prick did a Reverse Canker in there...
Mark: Why, John?

After recieving a B.O Job, you take your salty/sweaty dick and stick it into the girls mouth. This move cannot be done unless first recieving a B.O Job.

Friends: Thats gnarly bro, your the first person i know who has given a Canker Cleaner!

We were having the greatest night of our lives until those 2 canker sores showed up and they wouldn't leave. It always takes too long for a canker sore to go away.

A dry bit of snot hanging down from someone's nose. You know the thing, you just can't take your eyes off it and you know you should tell the offender, but you can't.

A sore one gets when he forgets to wipe his anus and then precedes to participate in athletic activities. The sore is generally very rashed and dirty. While the only cure being human saliva, one must physically eat his own Kentucky Canker sore out of his asshole or ask a friend/relative for assistance.
When Fred couldn't bare his "Kentucky Canker Sore" anymore he just decided to call up his buddy Tim.
