mafucka 

As said by J-Roc on "Trailer Park Boys", a mafucka is the urban bastardization of motherfucker (q.v.) however its use can vary widely, see example:

"Game's postponed because no mafuckas can go to Canadian Mafucka and get a new orange mafucka for $2.99 !?"

Hakuna Mafuckit 

\ˈhəˈku'nə-'mə'fʌk'ɪt\
│huh-koo-nuh muh-fuhk-it│

The phrase is derived from the Swahilian phrase "hakuna matata", which translated literally means "there are no problems", and the English phrase "fuck it".

:to quit or be done with something that was giving you worries or problems.

:to not put up with anyone or anything's (bull)shit or drama anymore

Hakuna Mafuckit is a wonderful phrase and a problem-free philosophy that promotes a very chill, laid-back, anti-dramatic type of atmosphere.

Josh: "This chemistry work is giving me problems man! What should I do?"

Dylan: "You're still doing that shit? I quit trying to do that shit a long time ago. I said Hakuna Mafuckit to it."
