When a girls pussy(or ass) is sooooo large you could stick your entire fist in it. Then you pick her up with your forearm inside of her using her similar to a wristwatch. Very difficult to perform but when it is done, you know you got a loosy on your hands(literally).
That broads vag was sooo used I pulled off a Harrington wristwatch on er'.
Forcing a girl to make out with her friend just after she sucks your dick. While she is in the midst of sharing your kid candy, you take both of your hands and shove them into each girls ass applying what is known as the Harrington wristwatch. Believe me, it makes your boom boom go zoom zoom.
He was just about to apply the Harrington wrist watch, when he thought, I should give her and her lady friend a grens the good ol' fashioned way to start things off right!
