Being so mentally deranged and exhausted from years of masturbating to porn that you have turned into an absolute sociopath, plagued by anxiety and loneliness. Your only pleasure in life is ejaculating to porn several times a day. Slang for what a normal man does when they have an orgasm is to cum. What the porn addict does is to COOM.

A term used to reference cannabis/marijuana/weed.

A coomer, (Pronounced COOM-er), is an elusive creature that spends its whole life desperately trying to reach the next best nut. It is classed as a critically endangered species. The coomer was once thought to be nothing but fiction due to the rarity of these beasts.
Not much is known about the habits of these elusive creatures, but they are said to reside in tiny rooms that reek of mildew and B.O., floor littered with custom-made waifu pillows and the coom of the coomer itself. They are said to be mostly solitary, though there have been half a dozen cases of supposed coomer packs being sighted in the wild.
It is said that, if disturbed, the coomer will become enraged, and will attack the offending creature. It has been reported that a coomer may even coom upon its enemies, some say even stuffing them into homemade COOM jars on occasion.

A man, typically in his 20s, who's sole existence revolves around Cooming.
