[alt text: a pair of posts by strudel-fatpaws on tumblr. The first post says, "who was the guy who said every indie game is named either 'empoisoned' or 'swumbles big jumble'. i swear this is a real thing someone said". The second post says, "gonna start sorting my steam library like this". Included with the second post is a screenshot of a Steam library, in which games are sorted into two categories titled "Empoisoned" and "Swumbles Big Jumble". Under the "Empoisoned" category, the games listed are: "Antichamber", "Balatro", "Pseudoregalia", "ULTRAKILL", and "Wobbledogs". Under the "Swumbles Big Jumble" category, the games listed are: "The Binding of Isaac Rebirth", "Orbo's Odyssey", "Patrick's Parabox", "the Gnorp Apologue", and "Will You Snail?".]
The Swumbles Big Jumble naming scheme can probably be traced to ZX Spectrum games coded by 15-year-olds in northern England in 1983 or so
Even earlier, Colossal Cave Adventure from 1975 is the earliest one I can think of.
Likewise Dungeon from the same year might be the earliest Empoisoned
EDIT: Nah, Pong predates Dungeon.
One of the first arcade games (1971) was Computer Space. Kinda feels halfway between the two, so that's fun.
EDIT 2: Think I found the earliest Jumble's Big Bumble: Hunt The Wumpus, first distributed in May of 1973
