Gak
When you throw up so hard, it feels like your stomach is doing a backflip and your brain is doing the twist. Or the actual mess you leave behind.
'I gaked so hard, my brain is on vacation and my stomach is doing the cha-cha.'
'That gak was so bad, I left a trail of vomit and regret.'
'Gak is the reason I missed my favorite show and my mom’s favorite song.'
