noun | gas lim·it
The gas limit is like the bouncer at the club - it's the maximum amount of gas (or computational effort) that you're allowed to use in a single transaction. Try to use more than that, and you'll get kicked out on your ass.
Example
"I was trying to mint this new NFT collection, but I forgot to set a high enough gas limit and my transaction ran out of gas halfway through. Now I'm stuck with half an NFT and a whole lot of regret."
"Setting the gas limit is like playing 'The Price is Right' - you want to get as close as possible without going over, or else you'll end up wasting a bunch of money on gas fees. It's a delicate balance between being cheap and being stupid."
