The phrase originates from Wolfville, Nova Scotia.
Used to describe a female of adequate attractiveness that would likely be shunned in many bigger social situations.
The phrase is usually used to exaggerate a woman’s attractiveness, to reach a level that is suitable for a male to recollect his sexual act and prowess to his male counterparts.
When combined with liquor these Wolfville 7's are the most dangerous; this is when they like to pounce on their prey. This is a result of them appearing much more attractive in the dim lighting of a liquor establishment.
"Hey bro, you take anyone home last night?"
"Yeah, I did."
"Was she hot?"
"Ummmm, ......ya......... she was a wolfville 7".
