So we're supposed to just go to his profile and say something like, "This will happen to you when you're roasted!"
No. Read through the thread I linked to in the first post. It is a roast. You poke fun at the guest of honor aka the roastee who, in this case, is Strop. Only those who have been active for at least a year and/or know Strop can roast him and will make a post doing just that when the roast officially opens.
