A 'unicorn' or 'unicorning' is London slang for consuming nitrous oxide from a balloon around shortly (normally 5 - 10 minutes) after having snorted a line of the illegal substance ketamine. Ketamine is wrongly known to be horse tranquilizer and symbolises the horse part of the unicorn. The balloon symbolizes the horn of the unicorn. To say 'praise the unicorn' before inhaling the nitrous oxide is very common part of the ritual.

Unicorning can also refer to the short but intense trip like state an individual is in when having combined both drugs.
'Let's do a unicorn!' or 'We were unicorning a lot last weekend.'
