Below may help, it's from a thread called Team Focker Watch
It all started with one woman's dream... a dream of finding a way to non-verbally acknowledge a fellow DISer across a crowded park...
Summer 2006: a terrific DISer named Lisa posed the question of how to acknowledge all those Lime Green Mickey Heads (LGMH's), lime green
Crocs, lime green Baggallini's, lime green DISERS, when one is standing in line or otherwise unable to engage in conversation.
The answer? Robert DeNiro's infamous "I'm Watching You Focker!" gesture from Meet the Parents, now known as the LIME LOOK!
What followed was the joining together of many DISers willing to give the Lime Look to other DISers. We've come a long way, baby! We now have official(ish) mascots to go along with our greeting. (See sorul82?'s Crocker Exchange thread to meet the mascots and take a turn!)
We are TEAM FOCKER WATCH!
