1. When someone is mysterious to you
2. When someone appears mischievous, weird or sneaky
3. Someone who has hidden motives or agendas; untrustworthy; eerie; odd
4. Sparking controversy probably appears sketch but it's different when you're sparking controversy intentionally; it's the ones who do it naturally that you have to watch out for.. That is where the essence of sketchiness lies.

Usually involving massive amounts of tracing paper, graphic design students often have to produce large quantities of these to present to their over-bearing professor (may be named Han). These are later displayed on a board with tacks, talked about harshly, dissed, crossed out and/or scribbled on. One usually needs to produce multiple sets prior to creating a computer image.

After completion of all the sketches, one must soak their hands in ice water, and take three muscle relaxers for the back pain. A writers callous may sometimes appear, however it will only grow to the size of an acorn.
"Professor Han gave us fifty sketches to do! Piece of cake!"

"Mad sketches kid."

"Tracing paper is really expensive, i wish i could eat and do my sketches."
