A scruffy, urban-dwelling homosexual hipster who passes for heterosexual.
I met a cute guy at a show the other night. He had tons of tattoos and a trucker hat and was sipping on some Pabst Blue Ribbon. I wanted to hook up with him but I soon found out that he's stromo -- he lives with his boyfriend Giovanni in Williamsburg.
One who is weird, does not conform to the norm, or is stalkerish. A sketchball can also be someone that does completely random things..such as eat french fries with mustard. Sketchballs are usually males.
Ewww, Bobby was totally picking his nose and staring at me, what a sketchball!
