Booty Sweat Rash 

Usually referred to by it's acronym B.S.R. A rash that develops, primarily in the South during the summer months, from an unfortunate combination of a poor or missed ass wipe and a prodigious ass sweat. Especially common among outdoor laborers and cyclists.

John never got a chance to do a proper clean-up after he sharted, so by the end of the ride his booty sweat rash was raging.

Seat Rash 

Sitting watching either a movie, a play, a speech, a sporting event, or any other event that would have you seated and you are bored and in your boredom you fidget in your chair to find a suitable and comfortable position to continue not enjoying what you're viewing.

When wanting to inform someone in your party of how you are developing a seat rash it is best to do so in a whisper for everyone knows that whispering denotes importance and if you whisper you have seat rash you will have their attention and no one else will hear your private conversation. Though if they know their Urban Dictionary those that are watching will know what kind of problem you are having.

*whispers* This guy is giving me a case of the seat rash. When is he going to shut up? Better yet when are we gettin' out of here?

*whispers* This movie is such a seat rasher.

Sweatlash 

During a raging concert, when someone in front of you whips their sweaty hair out of their eyes and lashes you in the face.

My eyes sting from the sweat of your sweatlash.
