Thundercats is one of the highest rated cartoons that came from the eighties. The cartoon was based on a large group of human shaped members of the cat family. On the island that they had to leave, Thundera, they were royalty and in leaving the planet they left all that they knew. They landed on a planet called Third Earth were they set up their new lives.
The Thundercats were not alone on the island. There was an evil mummy called Mumm-ra who with the help of his evil henchmen wanted to rule Third Earth and wanted to destroy the Thundercats. Lion-o, the leader of the Thundercats, took charge and with the help of his magic sword of Omens defended the plant and saved the other inhabitants from the evil rule of Mumm-ra.

Massively popular cartoon of the eighties. The only better cartoon was masters of the universe. Following a similar style to MOTU, Thundercats delivered some interesting storylines, and also tought the viewers a sense of morality. Something the power rangers generation didn't get.

Taken from the theme song to the 80's cartoon of the same name, a term used to refer to a "loose" girl. Note the lyrics to the Thundercats theme song:

Thundercats are on the loose
Thundercats are loose

Yeah, that girl is thundercats.
