^ A rush is something you do asap to catch your opponent off-guard in the early game. I'd personally say the term rushes are only valid within the first 10 minute of the game or so. If you tech straight to banshee's send them over to your opponent asap with cloak, that would be a rush. But if halfway during the game, you notice all your opponent has is just ultras so you plot down a few extra techlabbed starports and pump them banshees, that's countering your opponent.
Bancheese is fair-game. It's apart of the game and isn't totally game-breaking. There are ways to deal with it, people are just sore losers when they die to something gay
