Buttlark 

Someone who overestimates himself, believing himself to be something that he is not.
Origin: A friend of mine thinks he can "sing like a lark" but he sounds like ass.

Jonny is such a Buttlark, he cries like a baby, but he thinks he is really tough.

Buttmark

The soft folds of toilet paper that you place in between your buttcheeks as you stand up to give a courtesy flush so the cold water doesn't splash your sensitive baby soft skin.

After AV was done blowing the smelly pootinkies out of his garehole, he needed to give a courtesy flush so he placed a buttmark between his cheeks and flushed. His butt didn't get wet or dirty and the bathroom was no longer smelly, everybody wins, except your mom!!

Butt Bark 

Butt Bark consists of the stubborn pieces of turd that cling to the anal hairs and often refuse to let go.

While the rocking maneuver and pinch technique are favored strategies for dealing with Butt Bark, if an additional wipe is warranted, it is best to wipe in a front-to-back fashion to generate the greatest degree of sheer force and to avoid contamination of the genital area.
