look up any word, like cleveland steamer:
Half your age plus 7 is the mathematical equation to determine the creepiness of your dating relationship.
Person A: Is 20 years old.
Person B: is 18 years old.
10+7= 17
This relationship is not creepy because person B's age is greater than 17.

Person A: is 30 years old.
Person B: is 21 years old.
Person B's age is less than 22 therefore this relationship is creepy.

Therefore date someone who's age is at least half your age plus 7, or you're creepy.
