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.

Get the Dilisio blunder mug.
During the setting up phase or first turn of a game (primarily a board game), the player who's turn it is makes an overly aggressive and erroneous turn. The player doesn't recover from the mistake for the remainder of the game. This was named after board game reviewer from Dice Tower.
A player decides to found a civilisation in an arid desert.
Did you see that player's first move, a typical Dilisio Blunder.
