凡得瓦力人 Van-der-Waals-Force Person

非有緣至若化學鍵之婚姻以至於若氫鍵之友誼，亦非無緣至若無作用力之隱遁，而若即若離，縱橫人間者，即凡得瓦力人之謂。

The person who is neither affiliated by a chemical-bond-like marriage down to a hydrogen-bond-like friendship, nor alienated by a force-free-like reclusion, flitting around the world, is called a van-der-Waals-force person.
