It is expected that the small quantities of fluorides put into toothpaste can fluoridate the fatty acids present in almost all mammalian nipples, causing minute quantities of hydrofluoric acid to be released into the bloodstream. Normally HF is very toxic and bad for bones since it displaces calcium, but it is well established that low levels of HF over extended periods has proven to suppress nerve activity - hence the danger of HF acid burns since they are initially painless. This nerve suppression is believed to affect the brain, even in low concentrations, to produce a mild euphoria.

Toothpasting is a fad similar to huffing paint - a poorfag's way of getting high. It involves increasing the permeability of the skin on your nipples (either by rubbing them with an abrasive, or alcohol, a paint thinner, or nail polish remover), and then covering your nipples in toothpaste. A chemical from the toothpaste then absorbs through your skin and enters the bloodstream, getting you high.

It also works if taken as an anal suppository, but a tingly minty ass isn't as fun as tingly nipples.
Dude, I finally found a good way of getting into Sarah's shirt - I just told her I'd help her try toothpasting. I just rubbed her tits with mouthwash and then ten minutes of Colgate later we were zoning out.
