dumb dingo 

When a highschooler degrades a middle schooler or anyone younger then them by only a year even if they are smarter and more mature than them and all the highschooler says is bs. Or when a guy is being really stupid. You would call this highschooler a dumb dingo or and ignorant freshman.

Example1:

Katie: he just sent her a 136 texts in 30 minutes! What a dumb dingo!

Example 2:
Lucas: you're too young to understand, you're just silly 8th graders.

Bella: that's all bs you dumb dingo!

Dumb-diego 

A saying used to describe the typical “try hard” at the party. Usually can only finish 2 beers before throwing up. Typically they are less intelligent than everyone else.

That guy is acting like a dumb-diego! He was acting so cool earlier but now he’s throwing up.
