Sweanus.....after a workout, or hot summer day, or some steamy intercourse, the moisture that develops in the crack of your ass, is called, sweanus. More often than not, it refers to someone in the negative....because they may have actually just not showered in days, therefore creating a funky odor from 'back there'. Combines the two words sweaty and anus.....sweanus, VOILA!
Scene: Walking down the street with your friend, behind someone with a line of moisture on their pants (ya know, on the 'fault line'):

"Hey man, check out the sweanus on that back".

Synonyms: Plan B, Second Choice, Secondary Friend, Benched Until Needed
I got a call from X the other night. She had an extra ticket to a concert she bought for a friend, but they couldn’t make it so she called me to ask if I wanted to go because I am her Second String Friend.
