Agreed! Yet I dare anyone to use this sentence when the "Vous" form is required! :)

I dont want to get slapped in france so i probably wont be saying it

Yep, it's a lot better than "I eat butter" or "She eats sugar".

Haha

But of course because it's in french, it sounds wonderful. :)

"Vous mangez comme un cochon" "Aww you're so cute I didn't know you could speak French" (Actually happened with my and my girlfriend)

"T'es" is VERY colloquial to the point of being grammatically incorrect in French. Just an FYI :)

Comme means like (similar) and comment means how (question)

Comme means like and comment means how. Completely different words so now you know :) tu mange comme: you eat like tu mange comment? : how do you eat ?

sound? comme is com, comment is like common

No

You'd say: "you eat like a pig" which is a perfect translation of this sentence.

"tu manges comme un porc !" is the next stage when "cochon" is not strong enough to make your point.
