A cum beast is someone who is so extraordinarily horny that they don't seem human anymore

A term used to reference cannabis/marijuana/weed.

Cum Beast is an Epic Brawler in the popular mobile game Brawl Stars who attacks with a large hammer, sending a wave that can hit multiple enemies. Cum Beast also has very high health, allowing him to withstand a lot of damage. His Super can stun enemies for a decent amount of time, leaving them vulnerable to attacks from him or his teammates. His first Gadget, Active Noise Canceling, allows him to momentarily become immune to stuns, slows and knockbacks. His second Gadget, Irresistible Attraction, allows his next main attack to pull enemies he hits towards him. His first Star Power, Power Grab, gives him a damage boost for some time after he defeats an enemy Brawler and his second Star Power, Sponge, increases his maximum health for the duration of the match.
