A small penis the size you might expect on a baby.
Josh in our chemistry class has a baby winky. I know because I hooked up with him at the party at Betsy's house this past weekend. I had sex with Josh upstairs, but his penis was so small, I would call it a baby winky, some girls call it a baby dick or baby penis, but so small.
