Perhaps the unusual outcomes are just more memorable, and so
seem more frequent? Here's a representative sample of 30 that were used very recently.
Shoal, Hasty, Lobby, Vogue, Gunky,
Sheep, Theft, Linen, Slime, Fluke,
Hydra, Dizzy, Lance, Shred, Buyer,
Attic, Guava, Awake, Stank, Hoist,
Mogul, Squad, Roost, Skull, Bloom,
Mooch, Surge, Vegan, Scene, Cello,
None of those stand out as "WTF does that even mean", but maybe I'm the weird one if we adjust for age-demographics or book-reading.
If I had to guess at a riskier 20%... Guava, a fruit some people may not have had; Gunky because it's slang; Mogul, Vogue, and Mooch were borrowed from other languages; Cello is something people may have heard more than read; Hoist.
