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.

four square 

A school-yard game that is popular in Australia. It is similar to tennis. The court is a square divided into 4 equal sections and is usually drawn in chalk. 4 players each stand in their own square. Each square is a different ranking. The highest ranking is "King". The "King" serves the tennis ball to any of the squares. To score points, players must always bounce the ball in their square first, and then have it bounce in another player's square and either bounce out or bounce twice before they can return it to another square. The objective is to make it to King and stay there as long as possible. Variations include 2-Square, which is exactly the same rules but with 2 players instead of 4.

Four Square 

A sexual scenario in which the female participant is passed between four male participants in a similar manner to that of a ball during a four square match.

I double bounced Jenny so hard in a four square last night the three other dudes couldn't keep up.

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.

Quantum Four Square 

QFS is an adaptation of the old school playground version of childhood foursquare. Quantum Four Square is played on a square court divided into four smaller squares that meet in the center. The combination of worldwide styles in OS foursquare has led to an intense and competitive design of play using a tennis ball. QFS is gaining popularity amongst teachers and students in their classrooms. The QFS International Alliance Board of Representative Trustees is based in San Diego and run tournaments monthly.
