A piece of cloth used specifically to wipe and clean your anus whilst washing yourself.

The rest of my family may use it on their faces, but you’re actually holding my butt flannel.

a flannel 

A flannel is a girl who is butch and apears to be a lesbian. They have the stereotype look but may not even be gay.

They mistaked her for being gay but it turns out she was just a flannel and she had a boyfriend.

courtesy flannel 

The most necessary article of clothing when attending a movie. The flannel is then used to conceal any vulgar activities done underneath it. Therefore, one is courteous by using this article of clothing. Used as a prefix, courtesy can be applied to many other terms (courtesy pontoon, courtesy car, etc). Courtesy can also be used as a verb.

A courtesy flannel may be too straightforward on the first date.

“Wow, did they really courtesy on the pontoon boat? Classy.”
