people around you; thus excluding them from your conversation.
Civil engineering student 1: "Hey, check out that spiral reinforced column over there, I wonder what the dead

Civil engineering student 2: "About as much as I

Dumbass arstie: "Despite the jargoning, I understand you just burned your friend pretty good, huh?"
