First, it is officially allowed to write е instead of ё unless the meaning of the word changes (like все and всё). Still, you pronounce ё.
There are some who say that the letter ё should be banned from the alphabet, but personally I don't think it's a good idea.
As for the прёт - it's a 3rd person singular from переть.
Literally it means 'to apply pressure' or something like that (consider напор, напирать).
You can find this word in an idiom 'переть напролом' (to press through, to attack head on).
Смотри, куда прёшь! - Watch, where you're goind / driving (you idiot!) 'idiot' is usually implied

There is also a slang meaning:
Originally, I think this came from drug addicts. When he's saying 'меня прёт' this means 'I'm high', but later it became more widespread and
Меня прёт с этой музыки (Я прусь с этого фильма) - I like this music very much / I like this movie (I'm high from this music/movie).
