The opposite of “cap”. To mean the truth.
Guy 1: Bro youre more sus than me
Guy 2: That’s a cap

Guy 1: Nah, that’s an open lid.

Get the Open lid mug.
A position in sex dedicated to the defimation of women. You drop a big stinkin load in the toilet two weeks prior to meeting the cunt. Then, you hit it doggystyle over the toilet, slamming the lid on her head occasionally while she takes in the sweet aroma.
Tracy cheated on me last week so I gave her the open lid as revenge.
