Slaps

Definition:

Describes something exceptionally good or impressive

Context:

The musical "slap" is often credited to Bay Area hip-hop slang from the early 2000s, where a song that slaps is one that has a prominent beat (perhaps as if its deep bass metaphorically slaps you in the face, or it makes you slap the roof of your car in excitement). The phrase gained mainstream popularity in the mid-2010s through social media, where its meaning has broadened to describe anything of high quality - from food to fashion to entertainment (e.g. "this X slaps"). Sometimes it's used casually / ironically when applied to mundane items like sandwiches or everyday experiences.
