I find “Top 10 Yo Mama So Fat Stupid Joke List” including ‘Yo mama so stupid that she got hit by a parked car’, “Top 10 Yo Mama So Fat List” including ‘Yo mama so fat she put on her lipstick with a paint-roller,’ and “Top 10 Yo Mama So Ugly List” including Yo mama so ugly when she died she went to Heaven and God said I didn’t creat you,’ on an website.
Based on Google Ngram, the word, ‘yo mama’ and its counterpart, ‘yo papa’ came into use in circ 1935 and their currency started to show a sharp rise from around 2000.
Although none of Cambridge, Oxford, and Merriam-Webster English dictionary registers the word, either ‘yo mama,’ or ‘yo momma,’ Wikipedia defines it as the alternative form of ‘your mother.’
However, when ‘Yo mama’ is used as in ‘yo mama jokes,’ it appears to me that the meaning of ‘your mom’ drops off,’ and turns into a generic, any (fat, stupid, ugly, —) woman-related jokes. Am I right?
Is it possible to extend ‘yo mama (papa) ’ to other subjects such as ‘yo mama (papa) episodes,’ ‘ yo mama (papa) lessons,’’ yo mama (papa) saying,’’ yo mama (papa) blunders / guffes’ than ‘yo mama’ jokes?
“Yo mama” does mean “your mother.” The “yo mama” jokes are more or less humorous insults, used as a sort of verbal sparring on the street. Without going into its origins, the way this arose amongst those who created it was this: a person’s mother is sacrosanct, an untouchable icon, so insulting someone’s mother was a particularly effective way of getting the better of that person. What you are seeing is a watered-down version for the purpose of making it more generally accessible and more humorous, so the reference to someone’s actual mother is diminished, but not to the point of turning it into generically “any woman.”
And given the nature of the material, I for one can’t see it being extended into other versions such as the ones you suggest.
