Just looking for some help translating the following.

"You're a liar and you know it. You're ugly and wrongly assume you're smart. I would like to smack you in the face... I really, really hate you."

^_^; It's for a little story in which someone sings these words... I'll be entering Gaeilge classes sometime next month, but I don't think they'll teach me this sort of thing.

No worries, though. I have no intention of learning the terms/phrases to fly over to Ireland, run around the Gaeltacht and ignorantly spew them at strangers.
