peeps is people, I use it, as well as peepettes for ladies :-)
Sometimes I even say goodly morning rabble.
Sweetpea is me, it's a nickname that Welshyorkie has for me, I call him Sweetcheeks.
Beejay is Hotshot and so on and so forth.
Not a clique, but when a group of people visit the a thread at the same time, you become familiar with them.
