SHUMDIES 

Male ejaculate mixed with heavily soiled underwear. Shit, cum, undies when effectively combined make the tri-hybrid noun shumdies.

"After busting in a ripe pair of soiled undies I mailed those shumdies to my best friend to check to see our friendship compatibility ".

shundies

Simply means, shitty undies (like when you shit yourself (literally) and you get all shit in your undies.)

Dude, after I went on that rollercoaster...I GOT SHUNDIES!

Shundies

Underwear that you keep in the back of your drawer just in case but they are no longer part of your regular wardrobe. IE they are ugly and your partner doesn't like them.

I have a bunch of underwear tucked away that are shundies because my boyfriend thinks they are too saggy.

Bob says to Billy, "Yo Billy, i bought us a six pack for the game"... Billy replies "SHUNDIES in your UNDIES" - with the accent on shundies and big ending on the undies!!

Shumbies

A period of time after you haven't slept for over 24 hours whilst having been on a drug binge and the paranoia starts kicking in whereby you think people are talking about you, cops are nearby, but mostly general paranoia.

Can also be a competition to make your friends go bad and freak out.

Check Tommy going shumbies over there in the corner chewing his fingers off. Old shumbledore himself.

Some people just wear those shorts that are SO short they might as well be undies… Shundies.
