Acronym in the internet startup community for "you only hit one million once", referring to obtaining your first million users.
Originates from yolo, but instead of the battle cry for moronic decisions, events prefixed or suffixed with YOHOMO tend to be related to first world problems.
Jason: Our 1M user party is going to be a disaster: we're out of fridge space for the Svedka.
Matt: Bro, just expense a new fridge. #YOHOMO.
Idiom to not worry about something. Literally comes from the desire that someone not secrete a button about the problem, because that would be really painful.
Hey, I'll take care of updating all the paperwork. Don't you sweat a button.
