HTBP 

“Here There Be Pee”
A tongue-in-cheek cartographic marking to indicate where the explorers stopped to relieve themselves. Parody of the classic marking “Here The Be Dragons.”

Harrow, in consulting the map, saw that Sterling had marked the spot twenty yards from where they had eaten lunch, ‘HTBP’.
