When you run a 5k(3.1 miles) then take ice baths after. Often mistaken for its derivative Netflix in chill referring f*** but no it means just run and take an ice bath. So shut the hell up football players and stop saying you wanna "5k and chill" with the cross country team
jim:" hey susie wanna 5k and chill"
susie:" sure"

* runs a 5k then takes ice bath and no they did not "do it"
