A toilet prank in which someone craps on the rim of a toilet and then shuts the lid so that when the crap dries the lid and rim become stuck, creating the "brick and mortar effect". This prank is designated by the vertical clap of the hands, and is usually accompanied by an upper deck.
At wrestling camp, all the freshmen were pissing me off so I broke into their room and brick and mortared their toilet. They couldn't get it unstuck so they made Carlino clean up the whole thing and he started crying. What a bitch.
