Performed by only the biggest of mooks, the mook boot, is a boot to the head while a fighting opponent is on the ground. The grounded opponent does not necessarily need to be the mook's fighting opponent. Actually, the biggest of mooks use gorilla warfare tactics by running into a scrum, booting a random person in the face, then retreating into the crowd. The mook boot is always performed by the biggest bitch in the vicinity. The mook boot is the ice bucket challenge for a mook. They just can't help it when someone is recording.
Quick, scan the crowd for the biggest mook. Once someone hits the floor, he will step up to the plate and deliver a mook boot then instantly disappear into the crowd like Ray Liotta in Field of Dreams.
