-slurring your words enough to combine the words "mother" and "fuckin'" to create one cohesive compound word, which in turn, increases your ability to flow when cussing someone out
Sounds like you're saying a swear (mothafucka) but really means something different. It also can be used as a coverup for accidentally saying 'mothafucka' infront of a teacher or parent.
(boy playing video games) - "muhhfugga!"
mom- "did you just say mothafucka?"!"
boy - "NO. actually i said muhhfugga!"
mom - "mhm. and what does that mean?"
boy " a stupid ugly person. duh"
mother *with a confused face* "oh..."
*walks away*
boy *saying in his head to his mom* - "yeah muhhfugga. bet you feel stupid now." :)
