glow-ler-coaster
When you've "glowed up" a couple of times, and you've also "glowed down" a couple of times, but you're still a bad bitch!!
"Yeah, I lost 200lbs and got rid of my ache, and yeah, I've put 80lbs back on and am not looking as fresh, but to paraphrase Ronan Keating 'Life is a glow-ler-coaster, you just gotta ride it'. You still can't fuck with me!"
