noun | gas fee
A gas fee is like the cover charge at a nightclub - you gotta pay it to get in, but once you're inside, you're free to party your face off (or in this case, send transactions). It's the price you pay for using the Ethereum network, and it can vary based on how busy the club is.
Example
"I was trying to buy this sick new NFT, but the gas fees were higher than my rent. I had to choose between owning a jpeg of a monkey or having a roof over my head. I chose the monkey, obviously - YOLO!"
"Gas fees are the reason I'm stuck holding these shitcoins - every time I try to sell, the fees eat up all my profits. It's like trying to leave the casino with your winnings, but the bouncer keeps taking a cut every time you walk out the door."
