Sketchead 

A sketchead is British slang for a douche-bag. And the stereotypical douchebag thing to do is to turn up to parties uninvited.

Also a song by Arctic Monkeys, from the album "Cornerstone"

"David is such a sketchead, doesn't he realize we never invite him to anything for a reason?"

Sketchy Tom 

This man is the sketchiest being in existence. He is the Sketchy OverLord, and if anyone opposes him, they disappear for all eternity. His face has never been seen but it is said that his hair glows like a matchstick. The brighter it is, the more souls he has consumed.

Person 1: Bro, my brother opposed Sketchy Tom!! He has disappered!!
Person 2: I'll start putting together a funeral.

Shifty Shady or Sketchy 

Used to describe a person that can't be trusted.

A game where players take turns naming a person know by the group (associate, politicians, celebraty, family) all players respond at the same time with either Shifty Shady or Sketchy as their own opinion of the person named. If answers are not the same players then explain and defend their choice. The discussion ends with everyone agreeing to the same verdict after hearing all evidence presented. If no unanimous agreement then majority vote is the primary title and minority becomes secondary or (tendencies)

Out of Shifty Shady or Sketchy we all agree Mark is Sketchy with Shady tendencies. And we all agree Penny is straight up Shifty
