Overbetting: When to use it?

All the time I see people overbet shove with AA PF when they are 3bet. This accomplishes stacking KK and not much else, but I see more and more players do it.

I 3 bet AI w/ AA from the SB last weak against an UTG raiser and got called for 100BBs by AKo. This is 100NL. People just don't expect you to overplay AA like this, as long as you don't do it everytime, it works in good spots.
