A video of Drake playing with his snake on a plane leaked last month.

The assumption was that Drake leaked it himself, as the size of the snake was impressive.

Adam22, who has oddly made himself an expert on the male anatomy, pushed back on that during a chat with TMZ.

According to the podcaster -- who spoke to Drake about it -- Drake wouldn't have leaked the tape, as such explicit images are at odds with the OVO ethos.

Instead, he believes the leak results from a failed blackmail attempt.

As for what he saw ... Adam says he rates Drake's "missile" an 8 out of ten, explaining he's seen better on adult film actors.
