checking in on Foursquare long before your actual arrival at a destination.
Dude 1: 'yo you guys, scott just checked in so he must be here somewhere. we can order in a moment, hang on.'
Dude 2: 'cool dude, but i'm warning you, some of us are starving and running out of patience.'
15 min later.
Dude 2: 'Sumbitch! where is that dude? this is retarded!'
Dude 1: 'Damn bro, i get the feeling that Scott pulled a Premature Checkinulation. lets just order, fuck him.'
