Tanner: That party was so much fun. Seth's house is the best for throwing parties.
Jackson: Yeah, that was litty clitty.
Tanner: Tonight there is a party at Seth's house!
Jackson: Litty clitty!
The acronym for "out of sight, out of mind". The sharper minded of you will notice the added b, and this serves a double purpose. Firstly, it makes the acronym fun and unpredictable. Secondly, and more importantly, it turns the acronym into an alternate spelling for the greatest word in the English lexicon: Bosom. Noun. A woman's chest.
Seth: Oh no, we forgot to do an assignment for Stefano!
Jansen: Major boosoom.
Isaac: Can I eat at the caf today?
Seth: I will check if boosoom is working.
Zach: Oh no, I dropped some ice on the floor.
Seth: Just boosoom it under the fridge.
