A "thank you" given to someone for a favor or action that has not yet taken place and never ends up materializing.
You have already thanked them for something they did not really do. It is not fair and can be taken back at any moment.
Yesterday my wife said she was going to give me a message when we got home from work so I said "thanks, I really appreciate that". We got home, she ate dinner and went to bed with no message yet had already received her thanksism. I woke her up and took it back.
another term for a station wagon, mini-van, or any other kind of vehicle that is targeted at the "family" demographic(also M.A.V.)
"Tactical advantages aside, the M.A.V. is top of the line for the holy warrior troop transport manufactured by the Church of Latter Day Saints Military Industrial Complex. Also great for family trips...to heathen lands."
