LBT: that hashtag always brightens my day.

Bathtub Motor

A poorly engineered thing; particularly one that is over-complicated, with excess and unnecessary parts. The term comes from a Heinlein quote/novel.

"If one is building an electric motor, one uses only the parts needed to do so. You would not, for instance, add a bathtub simply because one was available."

"Why does this thing even have one of those?"
"It's a bathtub motor."

baiwy

Acronym for Bitching About It With You.
When two (or more) people disagree about how terrible something is, but want to rant at each other about it anyway.

Person 1: *posts a long rant about something*
Person 2: *posts an equally long reply bringing up different points*
Person 1: "Agreed! That's pretty much what I said!"
Person 2: "Yeah, I'm just baiwy."
