A situation in which ones undergarments are being sucked into ones anus. This will usually require going in after it by tugging on the outside of your jeans, shorts or costume. Sometimes a wiggle of the shitter will derail even the most stubborn of cobs.

Cousins Of Beauty; Two adolescent female cousins who think they are beautiful, so they flaunt their beauty; usually pose for pictures in the exact same way for unknown reasons.
example:
Passersby #1: "Who do those two kids think they are? They are doing modeling poses next to a major intersection!!!"
Passersby #2: "What do you think, Kyle? They are COB's!"

Get the Flake the Cobmug. Chip On Board (COB) Light-Emitting Diode (LED)
COB LEDs are basically multiple LED chips (typically nine or more) bonded directly to a substrate by the manufacturer to form a single module. Since the individual LEDs used in a COB are chips and not traditionally packaged, the chips can be mounted such that they take up less space and the highest potential of the LED chips can be obtained. When the COB LED package is energized, it appears more like a lighting panel than multiple individual lights as would be the case when using several SMD (surface-mounted device) LEDs mounted closely together.

Being multi-chip packaged, the light emitting area of a COB LED can contain many times more light sources in the same area that standard LEDs could occupy resulting in a greatly increased lumen output per square inch.
