To get (very) drunk

Also 'to go on the lash'.

Synonymous with:
Get pissed, get wasted, get hammered, get rat-arsed, get sloshed, get trolleyed etc

The word 'lash' orinally means to strike with a whip, and so has this extended meaning (ie. drinking makes you feel like you've been flogged).
NB. Usually used in a positive sense.
1. "Hey John, what are you up to tonight? The boys are all going out and getting lashed"
