Jovial mockery. When a friend does something particularly stupidly OR extremely well (thus making you envious) they are often lablled an fscunt.
fscunt is not a word for the weak, those who cannot interpret the above meaning correctly should avoid it at all costs.
NB. an animal can NEVER be an 'fscunt'.
Phil gee bro, i got 46% and that just sucks ass... man you're such an fscunt.
