スクショ sukusho

スクショ is what Japanese does to any long loanword: chop it to four beats and carry on. パソコン, リモコン, スマホ and エアコン were all built by the same rule, and once the shape is set it becomes a verb too, so スクショする is perfectly ordinary speech.

Culturally it earns its keep. Japan runs on screenshots: train times captured before going underground, a map saved because the signal will drop, a friend's recommendation forwarded as an image rather than retyped. And then there is the harder use, the screenshot kept as evidence of what someone said before they deleted it, which is where the word starts leaning towards 晒す.
