African rash 

When you are caucasian, travel to Africa, and get a crusty rash on the edges of each side of your pretty little mouth from drinking out of dirty-ass glasses. Generally coupled with a slightly swollen, evenly bumpy, pink rash on your right, inside forearm. The mouth rash is slightly swollen as well and a little crispy, while the forearm rash is of a consistent texture all the way through and is more soft and gentle.

I went to Africa because I had to, and after sleeping in a giant net, I woke up with a fucking African rash.

I knew I had the African rash because when I googled my symptoms, all the fake online doctors had no idea what I was talking about because they are all assholes.

Raider Rash 

Does not exist. Its a rumor that started because people will believe anything they hear. Texas tech STD rate is about 5% a year which is consistent with all the other Big 12 schools.

"Did you say Raider Rash? Come on man that shits not true."

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.
