Meffing 

a short form of, or rather, more polite way in saying mother-fucking. Derived from effing which means fucking by adding a 'M' in front of the word. Hence 'M-effing'

I've got three more meffing years til college ends!

Sarah told Kyle about Dustin meffing with people. Dustin told everyone a different state when asked where he was moving. Jackson said he wasnt meffing with him anymore though.
