A trap is a bend in the pipework that keeps a constant level of water in a drainage or waste system. This stops smells and fumes coming back up the drains and through your plug hole or toilet pan. Types of traps are bottle traps, P traps and S traps to name a few. Hope that helped :)
a "p" trap
In plumbing, a trap is a U-, S-, or J-shaped pipe located below or within a plumbing fixture.
A Vented Running trap with two clean outs or a P trap.
An S trap is not allowed in a plumbing system. Only a P-Trap
Turn on the the water to the fixture. And let in run.
One trap for each fixture and one main trap prior to leaving the structure
We don't as many model codes will ban their use
"P" Trap after that would be running traps
Yes, no problem

A trap house is a place usually in the ghetto used to sell all sorts of drugs and has nothing to do with plumbing, mice or rats
no, in fact most plumbing codes require a 2" drain/trap for washing maching drain.
