Is "reek out" Phrasal verb?

In colloquial speech you could say "he has reeked out the toilet" if someone left a big stink, yes. This might be a regional thing

I have never heard "reek out" "Reek" means "stink" but its usually a bit of a slightly "fancy" word, usually not used in everyday speech. When reek is used, its often used figuratively: "this reeks of corruption". Its also used in some slang dialects, usually the sortof "surfer dude" or 1980s-1990s teenager style, which Im not sure has a name. Slang example: "dude, that shit reeks!" In this context is is more often used literally to mean "stinks" Maybe you heard "freak out" which means to get really upset or stressed. Its an informal phrase.

Context please.

I could imagine this as something that could take hold if people started saying it (the way that we can "pit out" shirts if our underarms have sweat in them a lot, or how something can "stink up" a room), but I've never heard or used it.

I'll join the "no idea what you're trying to say" crew. Maybe you mean "eke out," as in to "eke out a living," as in "barely able to sustain yourself."

Usually, you can't replace "of" with "out". Off the top of my heard, the only phrases I can think about would be made the opposite by doing that, or just be confusing. So, "reek out" is not a phrase, and the replacement isn't grammatically correct. Very interested to hear how you thought of this, though!

It would be rather like "stink out" and "stink of". They mean different things.

No. Reeks of, smells of (extreme). Maybe you heard eke out. As in, I eked out an A on the test with the score of 93.

I have never heard this before. I'm not convinced that it's a native phrase.

I, a U.S. native English speaker, believe that I have never before seen these words used like this and hope that I never will again. Reek-Out® is an odor removal spray for sports gear.

Reek out is not a term known by natives (that i know of), but yes that structure is how phrasal verbs are put together. The typical term would be "reek of" something.

I'm not familiar with "reek out." you could say "reeks of" to describe a strong, unpleasant odor. like "the shirt reeks of cigarette smoke."

Never head of it.

I’m not familiar with that expression. Do you mean `freak out`?

No, this isn’t used. I see where you’re coming from, but it would feel redundant because “reeks” sort of already implies that something that the bad odor is coming “out” of the source.
