Abriviation for In The Groove.

In The Groove is an arcade dance game like DDR (Dance Dance Revolution). Two "pads" with four directional panels per pad are facing a screen, on which arrows will scroll from bottom to top, each arrow coresponding to a direction on the pad. When the arrow reaches the top of the screen, the player is required to step on the appropriate panel. Accuracy of the players timing is shown on each step.

ITG is produced by Roxor. There plan was to take the concept of DDR and make it better. DDR and ITG differ in many places. For example ITG has a three-dementional graphics system as opposed to DDR's two.

The first issue between Roxor and Bemani started over Roxor taking DDR cabinets and modifying them to play ITG instead of producing their own. That started a lawsuit that is still being battled in court.

Lets go to the arcade and play ITG!

An internet tough guy is a person usually male, about 35 years old living in his mothers basement on the internet that frequently makes threats about how much of a bad ass they are and makes claims of how much they've accomplished. The common internet tough guy will frequently say things like "STFU Noob", "Go fuck your mother, "your a fucking faggot", and so on.

"ITG >>>>>>> DDR," raved the elite who outgrew Konami's megahit.

Abbreviation of "In The Game", the number one rule to be in the game is to be single. And be a man basically. Never to be pussy whipped with any girl. And get as much pussy as you can forgetting about morals and girls feelings. The game will always bring a man happiness. And a good reputation between the bros.
