It's also "Server Name Indication", the piece of TLS that allows a single IP to serve multiple hosts by having the client signal the name they're requesting, and also "Secure Networks, Incorporated", my first dev job. You could just call it "snee!" (I advise the exclamation point as well), whimsically, and let people just deal with the weird etymology.

It's a big site! You stand a decent chance at introducing a new word to the lexicon!
