eyeball ping-pong

When two people are taking turns making awkward glances at each other but avoiding direct eye contact; Person 1 will look at Person 2, usually with a side-eye, until the Person 2 looks at Person 1, at which point Person 1 quickly looks away and the cycle starts over. The continuous back-and-forth resembles that of a game of ping-pong. Typically indicates some kind of tension between the two involved parties.
