An anapestic foot (known as an anapest) has two short syllables followed by a long syllable (SSL, or UU/).
Pentameter is five feet per line.
We were unable to find any examples of anapestic pentameter, so this is obviously not a popular combination. Please let us know if you come across any!
However, we made up the following two lines which, we think, is a perfect example of how an anapestic pentameter poem would read:
As we walked down the lane in the sweltering heat of the day
We saw men making hay in a field in the old-fashioned way.

U = short syllable; / = long syllable; | = division between feet
