English to Russian Art/Literary Music Pop song

Hello guys! Please explain me what 'lollipop' means in Britney Spears' Womanizer song? Can't find in any slang dictionary. Is it a guy who does what? Likes lollipops? Or is empty-headed? or big-headed?
Please help ))

Daddy-o, you've got the swagger of a champion
Too bad for you, you just can't find the right companion
I guess when you have one too many, makes it hard, it could be easy
Who you are, that's just who you are, baby

Lollipop,
[you must mistake me as a sucker]
To think that I, would be a victim of , not another
Say you're playing how you want it
But no way I'm never gonna fall for you, never you, baby
