A perverse sexual act involving two people, (one of which must be a male to receive the shit or the act would be classified more accurately as: space-docking), and the exchange of feces.

More specifically:
PartyA(male or female) takes a large to extra-large sized, firm, steamy(optional) shit into partyB(male)'s asshole.
Glenn likes when people shit into his asshole. (of course when it's a man on the receiving-end of this act it is referred to as Glenn-docking; when a female receives the shit into her vagina it would be classified as space-docking).
