[Lizzy Liz]

When you say youre going out to have some [cocktails]... but you really plan to get some tail.
(In [Laymans terms], you say youre just going to have some drinks at the bar/club/party, but really you [intend] to hook up.)
Or, if your single, then you say it when youre planning to go to a bar/club/party, drink alcoholic beverages, and get laid.

[Couch Potatoe]
