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.
