Lola you're a nut...Pendejo (I am not sure I have spelled that right) - idiot , Menteroso (again, spelling) liar

pendejo OR pendeja (pretty derrogative actually and idiot is a gentle translation. It actually means pubic hair LOL)
metiroso OR mentirosa (liar yep)

Could also go with puta madre, coño de su madre etc and my favorite is mama huevo LOL
