upper 90
General
American soccer commentary term for the perpendicular angle where the post meets the crossbar; the prime finishing spot.
updoot
Internet
An upvote, but said like you're talking to a puppy. Used ironically — nobody calls it an updoot with a straight face. The whole charm is in how dumb it sounds.
upboat
Internet
An upvote, but with a tiny boat instead of an arrow. Comes from the early-Reddit habit of giving out an ASCII boat — \o/ or similar — to good comments. Predates 'updoot' and carries a more vintage, 2010-era flavour.

General
Very busy, flustered or agitated; going flat out. Also 'the craic was ninety' meaning great fun.
