Top Definition
The condition whereby a group of people becomes significantly less able to accomplish some goal, such as going out to dinner or finishing a meeting, because no one can focus. Grouptarded gets exponentially worse the larger the group gets.
A(after waiting outside the dorms for 35 minutes): "Dude, we are gonna miss this movie--Adrianna ran back upstairs to grab her hair thingie, Pascal and Nadine just ran off to buy pretzels from the hot dog stand, Alex is detouring to an ATM, and Kellen fucked up his leg doing subway gymnastics last night so you know we'll be walking slow."
B: "We are so grouptarded."

A(during a supposedly 15 minute meeting that has stretched into 3 hours because of incessant chatter and constant interruptions): "Will you grouptarded assholes please shut the fuck up so we can finish this and get out of here?"
