active undercarriage rust protection

Marketing-speak for a chronic oil leak on your automobile - generally one that takes more effort to fix than the car is worth. Comes standard on most General Motors products since the early 60s, as well as Saab 900 series.

Click: Dude have you seen that grease spot on your inner fender?
Clack: Oh don't worry about it, that's just active undercarriage rust protection. Paid extra for it. I think.

funderwear

'Funny underwear'! The ones with a yellow smiley face on the front (and the back...), underwear that bears funny messages, ...

Funderwear is a complete no-no for real men!

underware

Underwear, made using tableware.

"Look at her 'underware' she's covering her breasts using dinner plates!" , " I like having pillow fights in my underware."

Undercarriage

If you are a little pudgy, your gut may sag down when doing push ups or copulating. This can be particularly unattractive as during vigorous sex, it may swing from side to side, back and forth, much like a metronome. In extreme cases, the folds of fat, or female breasts, may slap together making a sound not dissimilar to the sound of a sealion performing for food at shows at many zoos. This noise is known as flap or tat slapping.

"Dude, I was fucking Cindy in the ass"
"Awesome dude! How was it?"
"Great, but her undercarriage was swinging around, almost knocked me off balance"
"Eww. Sick dude"
