This segment where Seth Meyers breaks down "teen slang" on his Wednesday night show was not on fleek.

It all started a few weeks ago when Meyers and David Duchovny thought "bae" was short for baby (which it kind of is). Meyers then goes on a mission to explain how to use words like: "thirsty," "buh damn" (okay), as well terms I've never heard of, like "groupsie daisy," "whisperdick" and "hard-in."

If you're obsessed with learning slang, watch this and then never use any of these terms.
