Semi-bousy, anyone?

So I accidentally tripped over this word today. The OED was lying on my office floor. 

semi-bousy, a. OBS. Halfdrunk. c1400 Som vnlusty persone, pat wer not wele aswakid, or semybousy ouyr eve.

This juicy word must shed the dust of obsolescence. Go forth and speak of being semi-boused with your friends.
