“Psych” (2006 - ) is a TV series that follows escapades of a “psychic” detective hired by the Santa Barbara Police Department as an external consultant. Shawn, the consultant and Gus, his best friend-cum-partner are actually extremely observant detectives whose friendly rivalry forms the core of most funny moments on the show.

Most notable among these are insults Shawn uses on Gus, so as not to hurt him but to get his point across, lovingly referred to as Shawn-isms by the "Psych" fans. Here are a few Shawn-isms from “Psych”.
