or what?

Isn’t that so? This rhetorical question always follows a statement and serves either to emphasize its truth or indicate that its answer is obvious. For example, “Is this fun or what?” says emphatically that this pursuit is fun. As a slangy usage, it dates from the 1960s. However, the phrase can also be the last choice among a series of options, and this usage dates from the mid-1700s. For example, a diary entry by John Adams in 1766 stated, “In what is this man conspicuous? in reasoning? imagination? in painting? in the pathetic? or what?”
