(verb) The act of becoming so unhealthily involved with
one'
s significant other as to completely withdraw from the
world The person crawls up inside of their boyfriend or girlfriend'
s life much like the titular vermin, using only their large right claw as a doorway/camoflage preventing others from identifying he/she. The person only emerges every once in a while to nab a piece of
food (rejoin society briefly), and then scurries back into his/her hidey
hole. The culprit will continue to do
this until the signficant other is no longer hospitable or he/she outgrows them, then he/she will have to move on to another person, or find a tin can or
other such shelter.
