Do you wanna go halves on a bastard?
Heard in Waterford
One of the most despicable chat up lines that man ever invented... It is basically suggesting to a member of the opposite sex that you wish to copulate with them but do not wish to take part as a legal guardian of any offspring that might be produced from the activity.
Hey yungwan, ja wanna go halves on a bastard ya big slapper?
Hello young lady, would you care to engage in amorous congress without either of us assuming legal guardianship of any resulting progeny, you promiscuous wench?
