Someone who thinks they're smart by answering or replying with rude,
sarcastic, or redundant answers. The difference between a smart person and a smartass is that a smart person will answer you correctly without being an asshole, but a smartass is not only an asshole, but they're an asshole that gives you an answer
everyone already knows or they give you an answer that's half
right.
Person: "Compared to
2023, the year 2000 was a year with no pandemic, no mass shootings, no terrorist attacks, no smartphones, no social media, etc..."
Smartass: "You're an
idiot, bad things happen all
time, you're just not aware of it. Also, smartphones already existed, they're just clunky and not as popular."
Person: "I know that, smartass. I'
m just trying to make a point that the year 2000 isn't as bad as it is right now, asshole."
