The Hanson moment is a two-part moment.

The first part is watching the video for Mmm-bop and thinking "that girl's quite hot."

The second part is finding out that girl is a 12 year old boy.
John: Just watched that mmm bop video. That girl's not bad.
Jim: That girl's a boy.
Jim: There's your hanson moment.
