mercer-effect 

Synonyms: Matt Mercer Effect, Matthew Mercer Effect

Matthew Mercer is the Dungeon Master of the popular Dungeons & Dragons show "Critical Role".
The "mercer-effect" is what people call it when fans of the show get into D&D carrying the expectation that their sessions should be at least as good or similar to what they've seen in the show, not keeping in mind that the players seen on Critical Role have years of experience in both D&D and acting.

"I hosted a session with some 1st-timers the other night, they wouldn't stop talking about Critical Role and how we should try to play our game more like that."

"Yeah, that's the mercer-effect all right."

Roy D. Mercer 

A prank phone call character created by two Tulsa, Oklahoma morning DJs. Roy's gimmick mostly consisted of getting his victims mad enough to fight by telling them a story about how they owe him money. After tormenting the person, he would let them off the hook. They have at least a dozen CDs available. Then caller ID and star 69 ruined the fun for all of us.

My name is Roy D. Mercer. You sold my wife Sharon Jean a pager that blew up right on her butt. I'm coming down to get $300 from you today for medical billls and a new pager or I'm whoopin' your ass. How big a boy are ya?
