Verb - The act of recieving anal intercorse from a member of member of the clergy. The sex of either party is unimportant so long as the clergy member is allowed to perform the sacrament of commuinion. The eligibility of the recipient of the anal sex to recieve the sacrament of communion is not an issue in defining the act as a "caboose communion". Therefore, those recipients who are underage or do not themselves practise religion may still recive a "caboose communion'.
"They've been sending a lot of priests to the slammer for giving the alter boys the caboose communion."
