Gacha Cooler
A Gacha Cooler is a gacha person who hates heat and all gacha heaters. They're like the annoying little brother of the gacha world.
'I'd rather pull a 1-star gacha than listen to your gacha heater rants again.'
'If you're a gacha heater, I'll pull you until you're 1-star.'
'You're not a gacha fan. You're a gacha heater. Get out of my way.'
