GPA

An acronym that refers to the average of a student's grades in school across all classes; may have different scales in different school systems; e.g., a 4.0 ("four point O") is a perfect GPA in many schools.

Gpa is a somewhat common way to abbreviate "grandpa." Typically, people use gpa when discussing their own or someone else's grandfather, in chat and text messages.

For example, your mother might text you "Remember, it's gpa's bday this weekend." This is a reminder that your grandpa's birthday is coming up.

In some cases, however, people use gpa as an insult, just as they'd use grandpa. For example, if your GF thinks you go to bed too early, she may text you "OMG, you're such a gpa."
