Dude guess

Fefers to people (often men) who "claim something in a way that makes it sound like you know what you're talking about even though you're really only guessing". Originally from the Swedish word "killgissa".

- "Hey Laura, I need you to make a cake ready for me for Tuesday when the Republicans wins the election."
- "Come on, it's not for certain they will win yet. You are only dude guessing."
