Drinking excessively, especially during the week, and staying out until last
call. Usually needs to happen more than one consecutive night in order to
really count as Flintering, but getting completely blitzed can
still qualify. Originates in Ireland.
"Darrach, why do you look so tired? You have a big proposal
today!" "
Man, I've been Flintering all week. I'm
WRECKED!"
