In the pilot episode of Breaking Bad, in one scene one character (Hank) says that:
- Glock 22, that's my daily carry okay? I mean, unless you're talking, what, plus P plus loads, you can forget the nine mil, alright?
I couldn't quiet understand what he's saying. "What" is a conjugative word here but I don't get what place it does put "plus p plus loads" in.
"What" in this context is an interjection, grammatically similar to "like" in sentences such as:
He's been driving, like, one hundred miles per hour or so.
It doesn't impact the interpretation of the sentence, you can read it the same as if "what" wasn't there:
I mean, unless you're talking plus P plus loads, you can forget the nine mil, alright?
It just underscores that Hank is reaching for a somewhat exaggerated scenario.
(Also, "plus P plus loads" refers to a type of ammunition with a higher bullet velocity)
