blunder bus 

A blunder bus is where you masturbate. Taking a ride on the blunder bus is masturbating, and a bus movie is someone attractive that you think about while doing so.

That girl is real bus movie material, I gotta remember her for the blunder bus.

Dilisio blunder 

When one makes a mistake on the opening move of a board game and will not be able to win the game as a result. This is usually said in jest as in "I see you're placing the settlement on a 10 stone, that'll prove to be a Delisio blunder" (Catan) but can be serious "You bid 18 victory points to be the first player?!? On turn one!?! What a Dilisio blunder!" (Five Tribes). This phrase was coined during a Dice Tower Top Ten list posted on October 15, 2020.

Do you know that you just pulled a Dilisio blunder?

I'm just trying to avoid the Dilisio blunder here.
