implying that you will accompany someone to any event or gathering, and, usually without warning, not show up. Samming may involve a number of excuses.
5:30 PM (eastern standard time)- Pencek said he was coming over for wine and then then bar. 2:30 AM (timezone unknown)- Pencek most likely asleep in his bed, with no warning, completely samming all of us.
