Acronym for
Minor Attracted Adult - an adult who is attracted (usually sexually, but often in other ways as well) to persons who are legally considered minors. Most men are MAAs, because most men are sexually attracted to 16-year-old
girls, and in most jurisdictions 16-year-old
girls are minors.

Bob realized that he was an MAA when he noticed that every
time he had sex with his new girl friend, he was actually fantasizing about having sex with her 16-year-old daughter.
