The other day I decided I would stop saying quatre-vingt-dix (4, 20, 10 = 90) instead I would say huit-dix-dix (8, 10, 10) or even deux-quarante-dix (2, 40, 10) and shit like that

to add some context i forgot about it an hour after

Why not use the existing septante, octante, neunante?

Ask the guys in Modern times who decided that fick it we will go for the nonsensical method.
