There is no widely documented single origin for this short clip, so it is best understood as a piece of online soundboard culture rather than a line from a named film, show or song. Short vocal phrases like this spread because they are instantly recognisable, easy to reuse and flexible enough to fit many different videos. On soundboards and in short-form edits, a mama works as a compact reaction sound, passed between creators who use the same familiar hook to signal affection, silliness or playful surprise without needing any explanation.
