When you take a shit so long that it reaches the bottom of the toilet bowl while still attached to your butt.
Horace: Dude, what took you so long in there?
Boris: Sorry man, I was anchored to the toilet by my shit.
Horace: Damn, I hate anchor-shits.

When you feel compelled to do something but are anchored in place by the fact you are taking a dump or cleaning your rectum.
Bob: "Are you going to run up here and get your dog off my front porch?"
Me: "I would but I just cast off my shit anchor."
Bob: "Well hell, I understand, see you in about 3 hours."
