A chick that only appears around summer time and get's slammed by everyone before disappearing for the winter. (There's one in every hood)
Yo, I saw Summer Slam the other day, I had to pull over & get some, she was looking phat my cousin saw me dropping her off & offered to take her home, I guess he slammed her too.

Hook up for either a guy or a girl, with the intent for that specific hook up to only be there for the summer, and no longer than that.
"Wow there's last years summerslam, cant talk to her now, hide me"
