More questions!!

Hi peeps
I'm loving this website much to the annoyance of my wife who's not on the same excitement level as me yet hehe
Can I ask another few quick questions?
I always see people saying "In the Y" What does the Y stand fore.
And when people mention about checking in they say "We got seq12" or something like that?
Sorry if this is mentioned somewhere else on the forums and for being a complete noob
