Scalpoween 

When one is attacked and scalped on Halloween! A pun on Halloween.

Joe: I stopped at the motel on Halloween, and the bald proprietor burst in and scalped me!
Russ: Aw man, sounds like a Scalpoween!

salloween 

adj/noun – a pitifully weak attempt at celebrating Halloween

I thought their Halloween decorations were wimpier than my dentist’s: a couple of paper jack-o’-lanterns and black cats, with some cobwebs stingily strewn about – never seen such a salloween.

Swalloween

Holiday that comes once a year on October 31 that is celebrated by a woman performing oral sex on her partner until completion.

Most people celebrate Halloween on October 31, but in my house it's called Swalloween and I enjoy the day more than I would by eating some candy!

SWALLOWEEN

An annual gathering (in October), where 40 year old Pennsylvanian whiteys, who grew up in the suburbs, yet thought they were “gangsta”, drive/fly in from all over, to celebrate their friendship & relive their youth, by listening to 90s music, drinkin’ 40s, having politically incorrect conversations, eating, dancing, playing Cards Against Humanity, performing “personal joke” skits (which make fun of each other), & consuming A LOT of alcohol. These fools have their own Facebook & Snapchat groups, called “40s & Shortys”, which they watch the next morning, to be reminded of what exactly went down the night before. On occasion, they also try to gather for a Spring version of these festivities, called “Spitoween”.

Who’s grabbin’ the 40 for Swalloween?

Swalloween

Celebrated day of atonement for MILFS which parallels 'Halloween'.

Offsets Windows 10 issues, and lends credence to the value of good head.

Based on totally human API.

Last Swalloween, that chick from Oracle ran the house...the database is drained of errors now.

My MILF neighbor goes pro on Swalloween., and I like it.
