The act of masturbating and brushing your teeth at the same time. This can be performed in any setting.

Note:This act is mostly performed in the shower and does not always require crest toothpaste. Some have even double crested while engaging in the act of sex.
Guy 1: What the hell do you look so happy for?

Guy 2: I just did the double crest and feel fantastic!
