Loop
Any sequence of moves (or maybe even just one move) that repeats itself several times in a row, usually in a combo. Some famous fighting game combos are based on loops, like the Dust Loop in Guilty Gear, Daipan Loop in 3rd Strike, Paint the Fence in Capcom vs. SNK 2, and Run Stop Fierce in Street Fighter IV. If you're playing kusoge, you'll probably run into lots of infinite combos that use loops to sneak past certain game rules and keep the combo going forever.
