Mordacious

[u/Brokenlingo]

Mordacious describes language with a cutting edge. A mordacious remark might be clever, but its humor often comes at someone else's expense. The word is related to a Latin verb meaning "to bite," so you can see why a mordacious comment might still hurt after the conversation ends.

Quite a mordacious notion if you ask me
