The gastrointestinal phenomenon experienced by many people after they eat Popeye's Chicken including, but not limited to, explosive and watery diarrhea, uncontrollable flatulence, and upset stomach. Normally lasts until the next ferocious bowel movement.
We had Popeye's for lunch and now Amanda has a terrible case of Popass. It's EyE-ASS-Poppin' bad.
Describes many third-person console shooters where the gameplay is all about sitting behind some brick and shooting heads of enemies popping out from behind other bricks - one of the ways to cover up the inability to dodge and do precise shots fast with a gamepad. Very similar to pop-a-mole or a whack-a-mole game hence the term.
First appeared in Kill-Switch and was copied in many games since then.
"Wow shooting people in Mass Effect, Gears of War and GTA4 feels like popamole!"
