When one mistakenly thinks that one is alone in the house/apartment, and begins to do things one wouldn't do it one was with other people -- like singing, laughing at pictures of Hannah Montana, or fapping.

Get the The Shower Effectmug. While urinating into a lavatory, the main stream is entering as normal, but a shower like spray diverts and causes particulates of urine to land on the toilet seat. This is usually followed by a rapid wiping of the seat with toilet roll, often masked by the flushing of the toilet itself.

Get the Shower Effectmug. The shower bong effect is when you rip an average fart in the shower and you almost have to exit because of the intense smell.
