sas
noun: short for shitty ass; shortened from sass, so as to differentiate if from 'sass' (meaning cool or edgy). Following the UK name for the Special Armed Service (marine commandos) Sas also has connotations of venturing into dangerous places no one else would brave. Someone who does this is a sasser.

verb: to sas - to do someone up the arse, but using their own fecal matter as a lubricant.
That guy is one mother sasser! He sassed my sister thrice. SHe has a real sas, but I think she may have told him it was chocolate.

sas
The term is an acronym for the phrase "smiling at screen". This is to replace the commonly used acronym "lol" (laugh out loud).

This is used more in the business setting when talking via AIM or any other online chatting service. You in no instance will ever truly be laughing out loud while at work; you will chuckle at best.

Not to be confused with Britian's Special Air Service, S.A.S. refers to "sweaty ass syndrome", or ass-crack sweat.

Sweat from the lower back accumulates in the crack of one's ass (usually men) and forms wet stains on thier boxers, sometimes permanently if the sweat is mixed with fecal matter.

Usually treated with a "manpon", or wadded-up handful of toilet paper inserted into the asscrack.
