To be put on blast, i.e., have your personal business exposed to others, by a person via their Facebook status.
In particular when an ex post a status about you and tags 50+ friends so millions of people know your personal business.
I have a feeling from now on anytime someone posts somethinglike this and tags a bunch of people (which is brilliant btw) we are all gonna say "man did you see that? That guy totally got tubbed."
A term used when in a competition, one team or individual dominates the other with impunity. The inferior team/individual is said to have been "tubbed".
An action of ones parent aggressively throwing there child into a bathtub. After the child is in the tub, backhand them until they start to cry. Yell at them to drink out of the toilet. Then leave them locked in the bathroom for a month.
