To have the same exact vibe as someone. To be able to understand someone so well you agree with everything and know each other down to the bone. To be able to know what the other person is thinking and what they are about to say before they say it.
Abi and I pass the vibe check. We will be friends till the end.
An alert to when your attitude is being assessed. This alert can happen randomly, and anyone with a positive vibe is capable and obligated to check your vibe. Vibe checks allow gen z's to be more positive and nonchalant while making sure their peers are experiencing the same thing.
