What does 'Embrace the Suck' mean??

I suppose the closest translation would be "better get used to it.", または "that's the way it is, might as well accept it"

in alex's speech to the whole school he 発言しました beautiful people have a better life, and people who are ugly should realize that their life sucks.

i think it means that when other life's suck あなた don't feel as bad または at least Kyle doesn't

Embrace the suck, is a reminder that beauty truely does come from within.

"Embrace the Suck" is military slang coined in the Iraqi war that basically serves as an order and a replacement for "Suck It Up!" cause there ain't nothing あなた can do about it. Sorta like Windows 10. ;)
