1. One who has transformed his/her brain from a complex sensory-processing organ critical to life existence, to a mass of ill-functioning goo (squish) with excessive & unmoderated drug-use.
The term "squish head" appeared in the original Twin Peaks, S2 - E5; it was used to refer to the cocaine-running Renault brothers - who were from Canada - as "...glue-sniffing, squish heads...".

I'm totally getting side squish from my neighbor.
Meet a hot split tail at the bar I scored some side squish in the parking lot.
This bitch is making me crazy gotta get some side squish soon.

It means: beat the Miami Dolphins. However, after Dave Lundy published the novel "Squish the Fish”, it took on a perverted life of its own. In the book, Scooter thinks it means getting laid and pounding pussy.
After the Bills squish the fish and beat the Dolphins, I'm gonna celebrate at our tailgate party and squish my girlfriend's fish!
