A male of the human genus who can only have sex on the first Wednesday of the month and only in the the second half of the year ei, July-December. Greg can only fornicate with women named named Janice, Ellen, Diana, Bobbie, Sandra, and Lucy. If these requirements aren't met, his penis promptly falls off and has to be reattached with specialty imported superglue made from camel shit, horsefly eggs, chicken cheese, cryogenically frozen corn gruel, and the whipped RNA extract from the saliva of a pica patient's gum bezoar.
Greg's detachable penis will get him nowhere in life.
Greg must learn to have sexual relations with women with other names or he has a very slim chance of getting laid in the future.
My boyfriend's penis falls off unless I have sex with him infrequently under very specific criteria, he must be a Greg.
