A vagina (box) with a strong fishy smell, just like a fishermans tacklebox. Often caused by a bacterial or fungal infection, or a simple lack of personal hygiene.
adj. A term used to describe when a woman looks small when sitting down, to the untrained eye. However when they sit up everything falls out, fat rolls, tits, and/or ass. Derives from the commonly used fisherman tool the tacklebox, a small box that unfolds when opened.
i.e. she looked cute sitting down, but when she sat up, I had to tell tacklebox to tuck her shit!
