a phrase used to describe a word you can not think of because you don't know it. You use this phrase when you have no knowledge of the proper word to
imply that you have simply forgotten. With use of this phrase, you appear
no less intelligent, merely
forgetful.
1. "Hey Marvin, whats the name of that actor... the one from Forrest Gump?"
"Aw damn, I totally know who you are talking about, the name is
on the tip of my tongue..."
"Its okay, we all forget sometimes."
2. While playing
charades:
"Oh no! I can tell what you are doing! it is on the tip of my tongue!!"
