Taking a picture of your hand holding whatever you (and a few friends if applicable) are drinking with your current setting in the background- e.g. beach, concert, sporting event, party, etc.
"Instead of another dumbselfie where your faces are all blocking the view of where you are, take a Hollanding picture."
When a man holes up on his friends kitchen floor after carousing around like a drunken fiend; unable to care for himself. Usually occuring after heavy drinking and/or being an obnoxious member of a social scene at a venue serving liquor. A true Holmaning event will usually lead the person in the act to urinate on themselves and may lead to a guilt quilt the next day.
Kirk: Bro, you totally got drunk, passed out on my floor and pissed your pants last night. You're lucky I drove you home!
Tyler: Yeah, I guess I am guilty of Holmaning. My bad.
