When you get really frustrated, you would shout out that word...in nicer way.

Can also be use as "motherfuck"...in nicer way too. Can say "mothersparta" too.

Noting against Sparta!
John: MUTHASPARTA!!!
Susan: What's wrong, honey?
John: I can't figure out what 2+2 is!!!

Brain: Fuck!
George: Motherfuck!
Michael: This is sparta!
John: Muthasparta!
(Brain, George and Michael stared at him)
John: What? I thought it is a cool word!
