Nearly nothing related to the fact is mentioned, and the most sexual word used is 'foreplay' when one bot was setting up another to be knocked out.

In Season 3, the announcer refers to the bots being piled up as a "bot orgy"

The robots engage in battles with highly dangerous weaponry.

Very violent and intense battles. Sometimes sparks fly, tires are cut off, roblots flip, etc.

Mild swear words such as "hell" or "damn" are used, but not very much. Sometimes the builders do swear, as it is a sport, but everything is bleeped out.
