A creature from the depths of your nightmares. Starred in a youtube video. Has been known to have long pointy teeth, and his favorite melee weapon is "the claw," which he uses to rip peoples' insides out.*
Something that is generally psychotic can be described as schwelp-ish.
*He always is gleeful, and mirthful upon these occasions.
Your face looks like a schwelp.
This is schwelp music.
