Full Lid
Popularized by CJ in The West Wing and used by the real US press secretary to signify that there is no more news to be given to the press. Saying "that's a full lid" is a neat way of telling someone you are done talking about something or have finished taking questions.
Thank you for your questions, that's a full lid
Full-Lid
When you take a dump, and fill the entire bowl up to the lid.
"Bruh, trust me, I filled that bucket up to the lid" "whoa, you dropped a full-lid."
