Chancer
Heard in Wicklow, Kilkenny, Galway, Longford, Kildare, Dublin and Limerick
A dodgy, opportunistic rogue who cannot be trusted.
Yer man is some chancer, flogging dodgy books out of the boot of his car.
That gentleman is an incorrigible opportunist, peddling literature of dubious provenance from the luggage compartment of his motorcar.
