Check Baby
As defined by American rapper Future’s legal team, a “Check Baby” is "slang terminology describing a child conceived solely for the purposes of extorting monies from the father of a child in the child support setting." It was first coined in February 2020 by Future regarding his then-10 month old child with former partner Eliza Reign, whom he alleges to have had a baby with him solely to cash in on child support payments (or “checks”), hence the term “check baby”.
Future: Mann, that bicch Eliza takin my money, makin me pay child support to that Check Baby! Love that kid but damn that keeky ass trick female shady as fuck.
