PCS stands for Party Cosby-Style - when you plan for a night of debauchery that includes primarily alcohol and roofies. This may end up leading to sex that may or may not be consensual and conscious.
Abbreviation for Porn Cheerleader Sex. This is a code acronym for wild intercourse that involves blond lesbian pornography, sexy wife in cheerleader outfit and lots of great hot sex.
Imagine being in a public place with you spouse... “Hey honey, how about PCS tonight!?!?!” Now, if the question is answered in a positive way from the other person then great sex will be on both minds for the rest of the night.
