Bum Flower 

A playstyle between two players (typically in Plants vs Zombies Garden Warfare 1, 2, or Battle for Neighborville) both playing sunflower while using their heal beam on each other. They typically try to stay together the whole game and are a nuisance to deal with. If you are a bum flower, log off the game and go seek professional help.

Those bum flowers were a pain in the ass to deal with. This is the only situation where people actually play support flower.

A group of seven male friends begin a circle jerk on a rooftop in Southeast Asia. They simultaneously climax, then throw their legs back like synchronized swimmers forming a perfect star and tan their buttholes for 10 minutes.

Hey buds, don't miss the eternal bumflower this Sunday!
