What does tanked mean?
Tanked is the past tense of the verb tank, and its literal use refers to filling a vehicle or container with fuel or another liquid. A common example is a driver tanking a car before a journey. In informal and financial contexts, tanked also means to fall sharply or fail badly, as when a company's sales tank or its share price collapses overnight. This figurative use conveys a sudden and usually dramatic deterioration rather than a gradual decline. It is especially established in American English, though it is also understood in British English. Although the literal and figurative senses share the same verb, they can sound quite different: “She tanked the car” concerns refuelling, while “The project tanked” describes failure. The word's compactness makes it especially effective in headlines and reports of rapid economic or institutional decline.
To fill a vehicle, machine, or container with fuel, water, or another substance.
"He tanked the car at the station before leaving town."
This is the standard literal sense; in American English it is often rendered as “filled up,” while British English more often uses “filled” or “fuelled.”
To decline, fall, or fail sharply.
"Attendance tanked after the organizers changed the schedule."
This sense is informal but common in business, sports, finance, and journalism, particularly in North American English.
A single word can describe both a car receiving fuel and a business suffering a spectacular collapse.

Where does tanked come from?
The verb tank ultimately comes through English from the Indian word tāṅkh, meaning a reservoir or container, via Portuguese and earlier European borrowing. The literal sense developed from storing water or other liquids in a tank and later extended to filling vehicles with fuel. During the 20th century, especially in American English, the verb acquired the figurative sense of declining sharply or failing, probably through the expression of a business or investment “going into the tank.”
