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"
