Occurs when peeing late at night or early in the morning, (usually accompanied by an unfortunate boner) when the pee-er fails to turn on the light due to sleepiness - leading the pee-er to urinate in the darkness and get piss all over the floor.
Common responses include "fuck it" under the pee-ers' breath, but responses NEVER include cleaning the stray urine off the floor. (sometimes leaving the mother to clean it)
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
