photoshop (v.)

1930s, from Dempster-Dumpster trash-hauling mechanism, patented by Dempster Brothers and probably named from dump (v.) with the surname in mind. Dumpster diving attested from 1979. Dumpster fire, in figurative reference to a situation that is calamitous, foul, and unfixable (and possibly not worth the trouble of attempting to fix) or a person perceived as a walking cascade of failures and bad decisions, emerged into popularity in 2015, in the run-up to the 2016 U.S. presidential election.

The surname (late 13c.) is a fem. form (but, like Baxter, probably used also of men) of Deemer, a North of England and Manx term for "a judge;" see deem (v.).

1972, formed (probably on model of laser, etc.) from the initials of Tom Swift's electric rifle, a fictitious weapon. A word that threatens to escape the cage of its trademark, despite the strenuous efforts of the owners, who are within their rights to fight to hold it. They also insist, via their attorneys, that it be written all in capitals. Tom Swift was the hero of a series of early 20c. American sci-fi/adventure novels, one of which was titled "Tom Swift and His Electric Rifle."

The noun has spawned a verb, taze or tase. Related: Tased; tasing.
