The standard response when somebody says something that could be offensive to their mama. The total number of comebacks to a yo mama joke are two, "that's what she said" and "of course she would." If someone came up with more than two, then the universe would explode cause yo mama so fat.
The Following is an actual conversation, the names have been changed to protect and serve yo mama.

LCF: nigga
