WTW for a more personal (maybe even sexual) version of 'Glomp'

So I was watching a streamer on Twitch and she started talking about her days on LiveJournal and in the Harry Potter fanfiction community and she brought up the word 'Glomp' (To tackle-hug) and how there was a synonym for glomp that possibly starts with an 's.' This sounds so familiar to me and it's driving me nuts that I (and no one talking about it) can remember.

It's another fanfiction-y, internet slang word. All I'm coming up with is snog but I know that's not it.
