A modified version of the Shotokan Karate style with elements of Sumo, Wrestling, and Brazilian Jiu-Jitsu. This hybrid style of Karate was pioneered by Japanese-Brazilian Mixed Martial Artist and Karate practitioner Lyoto Machida in order to use his Karate style in Mixed Martial Arts fights.
Lyoto Machida used his Machida Karate style to knockout and defeat Rashad Evans to win the UFC Light Heavyweight Championship at UFC 98.
Used as a term to call someone who hangs on their boyfriend/ girlfriend all the time, thus acting as a "backpack".
This person is characterized by asking for constant piggy-back rides, always hugging, or attached in some way to their boyfriend/ girlfriend. This happens often enough to become awkward to other people near-by.
A Mochila is generally female due to "mochila" being a feminine word in the Spanish language, but is not at all uncommon in males.
