Random Riddle: 7-20-2014

Be enjoying the singles’ life most shall
We are more solitary than social

Of my body is constructed my home
A place where “guests” do not casually roam

After I am done giving it a spin
Danger is lurking for venturers in

The way I prey is a bit like fishin’
With two legs up on the competition

What am I?
