look up any word, like the eiffel tower:
A cross between a hard shell taco and a burrito. A filled hard shell taco is wrapped in a soft tortilla before eating - preventing the hard shell from falling apart in your hands.
(Taco hater) "I hate hard shell tacos... They are messy and always break apart in your hands"
(Mattaco man) "You're doing it all wrong silly... Here, have a Mattaco"
