A legendary rock song by the equally legendary early 70's rock band, Deep Purple. It is praised for it's quickly catchy beat, easy to learn lyrics, and it's Godliness all around. Considered by many as one of the best rock songs ever, and a favorite of many Deep Purple fans. A few other songs as good as this one are "Space Truckin'", "Fireball", "Black Knight", and "Demon's Eye".
A phrase describing something so incredibly confusing that you have no idea how to get through it. Comes from the Water Temple in Zelda 64, one of the most insane levels I've seen in any video game, ever. No joke - EVERYONE gets stuck in the Water Temple when they play this game, usually for weeks/months/years.
"What am I supposed to do next?! GAH! This is like being stuck in the Water Temple!!!"
Old folks from the country, generally in the south, use to say on nights where there was mist/fog over a swamp, pond, river or lake that the devil was raising hell under water. The saying "there is going to be smoke on the water tonight" came from that and means something is about to go down or someone is getting ready to raise hell. The saying predates the rock song by deep purples but I doubt they intended that meaning in their song. I believe their song is about a fire at a hotel.
If them MFs don't have my money theres gonna be some smoke on the water. I.e. I'm gonna raise hell.
