And What Part Will the Helmet Play in That?

Nerdy hipster to friends: You want nerdy? You know what I did today? I worked on this robot helmet I'm making on my floor. Yep, a robot helmet complete with LED lights -- for my girlfriend. See? That's love right there.
Girlfriend, explaining: I told him we could have butt sex.
Nerdy hipster, emphatically: But not until I finish the helmet!
