Here's my best try:
Pustoaico, nebuno, salbatico,
Hey crazy wild girl, (the best translation I could think of )

De ma afla iubita
If my girlfriend finds out
Imi fac cearta cu ea!
I'm gonna have a fight with her!
Laura:
Pustane, golane, nebunule
Hey crazy boy
De-ai sa cazi in mana mea
If you fall in my hands
Uiti de iubita ta!
You'll forget about your girlfriend!
Sorin:
Ce pustoaica smecherita a venit la mine
What a tricky girl, she came to me
Sa ies cu ea in oras ca-i place de mine
And asked me out 'cause she likes me
Sunt barbat bine
I am a handsome man
N-am refuzat-o si nu m-am ferit de ea
I didn't turn her down, nor avoided her
I-am acceptat propunerea.
I've accepted her proposal.
