You can't laugh at me, huh? (= You did the same thing as me.)
(or, it could be I can't laugh at you/them, huh? (= I did the same thing as you/them.) depending on the context.)
笑えねえ is a manly form of 笑えない.
~のこと indicates the target of an emotion, as in 君のことが好き, あなたのことが嫌い. You can think it as 人を笑えない here.
