Can someone please tell me what ахуенна means and if it is an expression and/or in which situations can I use it?
THANKS IN ADVANCE!
ахуенна = very cool! / great! /amazing! etc. This is an attribute (adjective) to something very good.
But this is foul / dirty / filthy language! It's used in informal speech, for example, among friends of your.
Example:
Не парься (=не беспокойся), всё будет ахуенно (=очень хорошо/very well)!
Фильм, который я вчера посмотрел - ахуенный (=классный/very cool)!

To put it briefly, that's the same very cool but it's used in informal speech.
