My wife and I were invited to a party at our friend’s place. The host’s brother-in-law was visiting and let’s say his manners were missing that evening. He behaved like a total pest - he hit-upon my wife and made crude remarks to the extent that his sister, the hostess, had to apologize to us - while he grinned that he was just “joking”.

Leaving the party would have been very insulting to our friend, the host - so my wife and I decided to play along. My wife refilled his alcoholic beverage extra strong and then urge him to a bottoms-up (finish the drink in one gulp) while I refilled her drink without any alcohol. His ego would not let him stop competing with my wife drink for drink and within a couple of drinks he was in the bathroom puking his guts out and no longer a nuisance at the party.
