Awkward Pass-by
When two or more groups of people talking amongst themselves pass each other and making quick eye contact but not speaking, usually among teens. The remedy is laughing loudly or pretending like what you're talking about is so absorbing you just don't notice the other party slowly walking by.
One group of gabbing girls pass a group of punks on the street, and they both vaguely know each other from the cafeteria but quickly look away.
GIRL: Wow .. . that was such an awkward pass-by . ..
