It's been a little over a week since becoming a forum member and I spent a couple of weeks lurking. Every forum has it's particular lingo that is unique to either the forum itself or to the topic it focuses on. Of course, many online forums share some of the same lingo and acronyms. So, here are a few that I picked up from here.
- Dog nose/snout - Not just on Fido
Dog house - Not just for Fido
Furkid - Fido 
Diesel Pusher - Not some seedy character on the street corner selling engines (Ok, I knew this one already from hanging out at RV parks)
Sticks -n- Staples - Hmmmm. Describes how my travel trailer is constructed and why I think I can do better myself with a bus. Why I'm here.
Those are just a few that I remember.
Add some more as you think of them. Serious or not so serious... doesn't matter.
 Fido/Phydo - generic name for a pet, not just for a dog.
