partying

[Anonymous]

"It's sad, isn't it? All these older guys partying way past their
prime."


I don't understand the word partying in this sentence
Is it comes from "are partying" or "who are partying"?
If it the present continuous, why doesn't "are" or "who are" is written before it?

"Partying", there, is the present participle of "to party". It is being used as an adjective there, modifying "guys".

party

intr.v., -tied, -ty·ing, -ties.
To celebrate or carouse at or as if at a party: That night we partied until dawn.
