A shortened term for a Shaladin- a person who ships Shiro with the paladins from the Netflix Show: Voltron Legendary Defenders. This is a problematic and dangerous person within the fandom because it condones grooming, pedophilia, and incest-like relationships (despite being fictional) considering the paladins all met Shiro when they were under 18 and looked up to him as an authority/brother or father figure.
"Hey what's wrong?"

"Ugh I just found fanart of Shiro and Keith in a romantic relationship. I hate shallie artists. I'm gonna block and unfollow this artist. I suggest you do the same."

"Got it."

When the bloke is about to cum, the Shally Whacking commences: the bloke rips his penis and balls out of her arse, and slaps her arse cheeks with his penis whilst cumming everywhere.
Tim "she's a dirty cunt"
Laura "how do you know?"
