Rainbow Dash contemplating the length of ponychan's bans.

Ten seconds flat is a general remark used when referring to a short period of time for anything. Ten seconds flat first appeared on the episode "Friendship is Magic: Part 1" in which Rainbow Dash stated she could clear the sky of any clouds in "10 seconds flat."

It first gained prominent use on 4chan refering to getting back from bans in a short amount of time, and since then has become relatively standard language but takes a back seat to newer memes.

Multiple variants of the meme is also made, for example, scootaloo, a young pegasus that idols Rainbow dash, has her version of 20 seconds flat to 10% cooler, a value opposite to Her.
