A guy who normally acts as if he is a hardcore stoner, and makes everyone aware he is so cool and interupts everyone so they hear his side of the story.
Guy: “interrupts reader”
Reader: “Hey man, chill you seem like an Ethan Flack right now”
Guy: “Sorry bro, I’m so fried right now”

Excessive teasing that leads to misspelling of common phrases. Oftentimes the teasee will get flustered and mix around words and letters to create a new variety with no meaning at all.

A Hack and Flack is an informal gathering of journalists (often called 'hacks') and public relations people (often called 'flacks'). This is usually off the record and involves alcohol. The purpose is to build and improve relationships between two groups who often work together but sometimes for competing purposes.
I heard Joe is coming to the hack and flack tonight, it would be good to hear him not spitting out rote talking points for a change.
