liquor that makes you 'lick her'. alcohol so strong it makes you go down on your female date regardless of whether it's the first date, you not being into that kinda thing, she not being very tidy downstairs or you even being a heterosexual girl yourself. variation of the word liquor. same pronunciation tho.
me and jen had some lick 'er last night and i got so buzzed i went down on her in the taxi on the way home! and i think she was expecting that because she took her panties off and put em in her purse before we left the pub.
