A term used when you are drinking something like milk or apple juice with company, but you want to act like you're in a fancy bar lounge. So instead of asking for your buddy to fill your cup again you just say "Top me off, Scotty!"
bruh 1 : "Top me off, Scotty"
bruh 2 : "After 12 years of this friendship you still don't remember my name"
you: omg. last night i banged a fat dude. and it was amazing. his shlong was the coolest thing ive ever seen even though it had 3 fat flaps on it.
