10 Guy is a photo of a young man looking visibly stoned, heavy-lidded eyes and a slight smirk, like he's just had a profound (and probably nonsensical) thought. The format is used to share completely illogical, absurd, or nonsensical thoughts with the implied context that they might not make sense.

Part of the advice animals ecosystem, 10 Guy provided a comedic vehicle for sharing thoughts that were intentionally ridiculous or based on flawed logic. The name itself suggested someone who is extremely intoxicated or in an altered mental state.

Post the 10 Guy image with a completely illogical or absurd thought. The humor comes from the pure ridiculousness or the flawed logic of the statement paired with the implication that the person is very impaired.
