Flinch
Flinching, also called Hitstun is what happens to a character when they are hit by an attack. The character will be stunned for a very short period of time, usually just enough to interrupt any attacks or movements. There are certain attacks that do not cause flinching, and ways for a character to avoid flinching. The amount of flinching is referred to as hitstun. Some attacks cause flinching without any knockback whatsoever. It is used for combos in all 3 smash games.

In the original Super Smash Bros., hitstun was extremely high. This meant that this game had the most extreme and arguably best combos, allowing almost every character to have a 0-death combo.
In Melee, hitstun was lowered but wasn't lowered so much that it didn't allow for any combos, because it still allowed for several, such as the Ken combo. The Top, High and Middle tiers all operated mostly on combo ability.
In Brawl, hitstun was severely lowered, something that the game is often criticized for. The opponent suffers very little stun after being hit and air dodging decreases it even further, meaning that the game has hardly any combos.
