What it means
An oddball is the lovable weirdo who marches to their own beat, the colleague with the unfathomable hobbies, the one who says the strange thing in a quiet moment and means it sincerely. It's not an insult so much as a fond shrug, a word for someone who's just wired a little differently and isn't bothered who notices.
Usage examples

"Maya's a total oddball in the best way, showed up with a lunchbox full of homemade pickles and a book about shipwrecks."
"Don't write him off, he's just an oddball. Give him ten minutes and he'll have the whole table laughing."
Where it comes from
Oddball has been around in English since the mid 1900s for an eccentric or unconventional person. It joins odd with ball, likely playing on the image of a ball that bounces or rolls off in a way you didn't expect. The word stuck because it sounds light, teasing, and weirdly affectionate.
