My favorite is the last one: an
aggressively stupid person.
Nice.
Well, if you're going to do something, go strong and be aggressive about it!

Also note, the only difference between wiseass and smartass is that wiseass is considered vulgar slang, and smartass is only considered slang.
Huh? I can see a whole thread of philosophy/logic as to why wiseass is vulgar slang and smartass in only slang!?!
I think its something to do with: if someone is wise, it would really be vulgar if they were an ass too. Thats almost blasphemy--its kind of vulgar.
But if someone is merely smart and an ass, well thats not so bad. They are just a smartass.
If someone was wise, you'd think they'd be wise enough to know not to be such an ass.
Thus, if you are a wiseass, that is kind of vulgar.

Thats it, I've convinced myself (probably no one else, though).
A wiseass most definitely is not the same as a smartass.
