意味

LOL so hard, laughing my arse off — a vulgar, emphatic way to express intense laughter online.

クソワロ combines クソ (kuso, vulgar intensifier) with ワロ (waro, from ワロタ/ワロス, internet slang for laughing derived from 笑った). It expresses uncontrollable, intense laughter at something hilarious online. Part of the 2chan/5ch bulletin board culture that spawned its own vocabulary of laughter expressions (ワロタ, ワロス, 草, etc.), クソワロ is the 'I can't even breathe' tier of online laughter.
