1. This is any helmet that has a large cock/dildo attached to the front of it. The helmet should ideally have a chin-strap for extra added control. Depending on the size of the cock this item can really attract some great attention. It's a lot of fun to use too.

2. The head of the penis.

Aug 11 Word of the Day
A phrase to describe someone who is cognitively degenerating. Synonym of "going off the deep end". Can have varying degrees of severity.

Reference to the song "Hey You" by Pink Floyd. The line "and the worms ate into his brain" makes no sense in an otherwise linear and literal narration throughout the lyrics.
"My boyfriend has a total case of brain worms. He told me the cat was bugged so the Feds could listen in on us having sex..."

or

"You totally stumbled over that entire sentence. Can't speak English all of a sudden? What, do you have brain worms?"
