Raider Rash is a slang term for STDs; since Texas Tech University is known for its high STD rate (one in four people have STDs at Texas Tech,) and its mascot is the "Red Raider."

Noun: a friend who is usually only called upon by a friend when a more primary/prominent friend is unavailable.

Taken from the term “second string” in an athletic competition situation. In football, if the star quarterback gets injured during a play, the second string is called off the bench to replace him/her. A “Second String Friend” is essentially benched until needed, if ever.

Synonyms: Plan B, Second Choice, Secondary Friend, Benched Until Needed

Raider Rash is strand of STD's which comes from Lubbock, Texas. The disease is airborne but can also be contracted from bestiality (or similar animal looking creatures). It has side effects of painful urination, pustules around the genitalia, denial (see above), and will decrease GPA to a 1.0 which is still above average at the University of Texas Tech. The only cure is to quarantine infected areas (Lubbock) from the rest of the world.

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.
