A rating scale between 1 and 10 when deciding whether a woman is fuckable. 10 being gorgeous and instantly fuckable and 1 being an ugly pig dog you wouldn't wish on your worst mate.
I would rate her 2 on my tapometer, she is kinda smelly, with pendulous breasts and huge pointy dagger nipples, but enough beer and I would tap her.
A mental gauge that every man has that is used to measure the presence breasts in any situation. It may also be used to measure the quality of breasts.

A tachymeter (also tachymetre or tacheometer) is a kind of theodolite used for rapid measurements and determines, electronically or electro-optically, the distance to target, and is highly automated in its operations. Tachymeters are often used in surveying.
