Pierdol się, spierdalaj, odpierdol się - the most vulgar way Spieprzaj - something between fuck off and screw you, for some people it's vulgar and for another it is not. Odwal się - the same as spieprzaj Spadaj - the most 'kind' way to say it. The most common version between friends (in my case).
@victuuritrash All swears, that I wrote, are in an exclamation. Infinitive: pierdolić się (if you say it as a verb it means to fuck, to have sex or it can also be used as a verb to bother oneself with sth. When you're really tired and job is arduous you can use it. But then it's also a swear. Spierdalać - as a verb it means escaping from something really fast, still a swear Odwalić się - as a verb it still means fuck off Spadać - as a verb it means fall and it's not swear at all.
