foursquared
The completed project of becoming increasingly metrosexual while at the same time thinking you are better than everybody else. People who have undergone a foursquare transfromation can be seen with spiky hair, plaid button-up shirts, skinny jeans, and unholy amounts of piercings. Another tell-tale sign of a foursuared individual is that they feel the need to sing, although they lack the talents of muscianship and the ability to stay in key.
John use to be really cool, but then he got foursquared and no one likes him.
Foursquaring
A term used to cover for your presence in a place with which you don't want to be identified, indicating you are only here to get credit for a check-in.
Friend: Dude, why are you at a gay bar?
You: I'm just Foursquaring.
You: I'm just Foursquaring.
Foursquare
A mobile device application in which users "check in" to venues, businesses, and restaurants. Users can then see where their friends are as well as what locations are "trending" (heavily attended at the moment).
I just checked Foursquare and apparently Savanah just got here.
Foursquare Nazi
A person who will pass a judgement on your distant check-ins on Foursquare and question your ethics while calling you fake on the basis of your usage of a fun casual location based social network
