A couple of ideas from Matt, more to come...

Gandpar - "I have a guy..."

Used primarily in response to someone that requires technical expertise, especially when the person responding can provide the expertise in question. It comes from the infamous "Grandpa's Harem" photo, where Carley was photoshopped in by Grandpa's "guy." 

Larry - "You're very much!"

When we were moving Carley into her dorm at U of I, Larry stopped and held the door for a student carrying some of his stuff. The student, impressed with Larry's kindness said "Thank you very much." Rather than the universally accepted "You're welcome," Larry opted for the much less common "You're very much!" The biggest mistake, perhaps, was coming back to the dorm and telling the rest of us about it, because we've never stopped making fun of him for it.

Larry - "... rooned"

Synonym for ruined. Used when something is or will be broken by the actions of the user. First used when Larry bought Matt and Eric an adjustable basketball hoop in the early 90's. "Don't hang on the rim, or the warranty is rooned."
