It is an abbreviation of "suddenly pops out."

"Tone" + "a total mess": when your makeup (usually the wrong foundation shade) ruins your skin tone.

Smartphone + zombie — someone walking around glued to their phone, oblivious to their surroundings.

It is an abbreviation of "suddenly pops out."

Short for "your touch is totally dead" — said when something shows zero sense or flair and falls flat. The opposite of 감다살.
