A small sheep-dog that looks like a miniature Lassie. Sweet, playful and loves her owner like crazy, is very obstinate and nervous though, and males are very effeminate so these are not dogs for people who want a male dog for the sake of having a male dog (basically macho prats who want a protection dog) Everything else about this breed is positive just like the beautiful rough collie.
"Is that a baby Lassie?" "No its an adult sheltie, she's now 3 years old"

Get the sheltie mug.
A person that does not have an active knowledge and engagement with the larger harsher world. This distance from what most of us consider reality cause shelties to say ignorant and foolish, but mostly incredibly aggravating things.

a sheltered person
All these punk-ass shelties are up in my face.

And I said to the sheltie, "NO!!! YOUR PLACE IS ON THE FLOOR!!"

Get the sheltie mug.
The act of inserting a Sharpie or other pen/marker-like object into one's vagina.
Before Patch fucked Ashleigh, she took pictures of herself with her Sharpie in her vagina, therefore committing a sheltie.

Get the sheltie mug.
A shady young person whom lives or frequents a homeless shelter in the evenings and proceeds to hang around aimlessly or often disruptively until the Shelter reopens.

Scantily dressed teen girls with muffin tops and tramp stamps exposed. Overly thuggish guys with bad teeth and no future.

Underage girls yelling about performing sexual favors back forth across a street.
"The group of shelties is hanging outside the library again begging for change from old people."

"There is another pregnant sheltie having a smoke on her way to the liquor store"

"Tell that sheltie to put a shirt on and stop yelling, he's scaring the kids"
