The act of committing to go have drinks with the lads and then pulling out last minute to prevent next morning hangovers or trouble with the wife. There is a positive correlation between the above and Coitus interruptus.
Opposite: Brexiting - telling everyone at the party that you are leaving, but actually staying.

Nah, cunt’s pulled a coitus interzisgus. Said he had to work late. He’s just too slow or too stupid.
Or both.
Fuck yes mate! Fuck yes!
