Ink Blot 

When you stand up on the shitter before you wipe. The shit then is pressed between your ass cheeks thus giving the ink blot effect. When you wipe, it makes the same pattern on both sides of the toilet paper.

Dude, check out the pattern on the toilet paper from the ink blot effect I got when you knocked on the door!

Ink Blot Effect 

When one makes a bowel movement and stands up before wiping; thus, creating an image inbetween one's buttocks similar to that of the Rorschach Ink Blot Test.

Monroe made his ink blot effect concrete when he pulled up his pants and sat back down again.

Billy commercialized his ink blot effect when he headed to the copy machine afterwards and made 100 copies to sell to a psychologist.

Inkblotting 

To interpret an ambiguous situation in a way clearly driven by one's own beliefs, with a completely unjustified level of confidence. (Based on the inkblot test, also know as the Rorschach Test, in which an ambiguous ink blot is described by a patient, which aims to reveal content in the patient's subconscious that is nowhere in the actual picture shown to them.)

She declined a second date after the first one didn't go well - you were late, the restaurant wasn't so good, and you didn't really "click" - and you're 100% sure it's because you're overweight? Dude, you're inkblotting.
