At the moment, Sriracha is hot, at least if you happen upon the right drive-thru.
Can't say that I'd ever heard of it, however, until quite recently, at one of those drive-thrus (I ordered something else).
AFAIK, it’s a 21rst century “foodie” thing, that hipsters were into maybe 8 years ago and some still are. I’ve never had it and shan’t ever taste it.
I won’t eat anything that has a name with two consonants at the beginning.
It’s just unnatural.

They use it at Pizza Ranch. I hate it. Not because it’s hot, but some other disgusting flavor in it.
