In a maxmimum security prison, a new inmate is referred to as a Fish. During the first few days in general population the Fish will usually be anally raped by a larger inmate. Not knowing any better, the Fish will clamp his anus down and try and stop the rape from happening which will only prolapse his colon and require surgery and for his pooper to be sewn shut. Days later, when the Fish returns from the surgery ward with his colostomy bag in place, the same inmate will approach him, remove the colostomy bag and fuck his colostomy hole. this is the sweetmeat.
I'm gonna break that Fish's cornhole, then get his sweetmeat.
