beverometer 

1)You place your cocktail on a coaster and, due to barometrical conditions measured by this activity, the glass sticks to the coaster....but invariably falls off as the above mentioned beverage is halfway to your mouth.

It was a hot and sultry night as Chad, forever the suave and debonaire bon homme, raised his glass to toast his admirers but the beverometer ruined his moment by dropping the coaster squarely onto his nutsack.

bonerometer 

The name for your penis when you achieve a hard on right before a rainstorm.

Suzy says..."Bobby why is your dick hard?" Bobby replies..."It's about to rain." This is my 'Bonerometer!'

Beerometer 

An internal instinctual device that one uses to determine the amount of beer left ion a partially consumed keg.

My Beerometer tells me there are 227 ounces of beer left in this keg.
