A party in which people get naked and writhe around while people shit onto their bodies and into their mouths. A way to discern such a party (aside from the shocking whiff) is the presence of either a drained hot tub/swimming pool or several large inflatable paddling pools dotted around the premises.
Rachel was invited to a scat party in Hampstead. She was only too happy to go as she knew the hosts and they knew she loved her Jazz music. In fact, she counted Ella Fitzgerald as one of her favourite artists. Imagine her horror then when instead of people standing around drinking and informally chatting, listening to supremely gifted vocal Jazz musicians she instead walked in on a scrum of about 50 people all in various states of undress, sploshing about covered in human excrement and orgiastic excess. Being brought up rather well, she knew it would be rude to leave so got into the spirit of the proceedings. It wasn't long before she was on the receiving end of a particularly vicious Cleveland Steamer, administered by a punky looking young woman called Carol who was an administrator at the local hospital. She finally left at 2.30am however she vowed to never attend again.

A phrase used by people on xbox live who encourage other members of xbox live to hold frequent scat party's. A scat party consists of joining xbox live ranked or player matches and wanking whilst playing with pre-prepared excrement (it is not a requirement that the excrement is your own).
A frequent scat party member M.Cline had this to say "scat party's are so underated, the feeling of shouting acheivement unlocked as you release your load, and everyone who is online going 'cool what one did you get?' is unprecedented"
