Keez is what you would use to refer to a group of close mates, or can be used when talking about a group of mates that are in prison (under lock and key).
It’s another way of saying the plural of the term “G” which means close mate. In this case keez is the plural of the term “kee” which is basically someone who is even closer to you than a g (they are called a kee because they usually would know your secrets, like a key opening locks)
“I only let my keez know about dem ones you get me”
“3 up my keez”
“I’m gonna meet my keez this weekend”
“Me ‘n my keez are heading OT this week”
bastardization of keke, which is a bastardization of hehe, which is more or less a chuckle. Used online and only online. Refer to rooflesfor more insight
Presumably from Genmay or Penismightier.com forums, keekle is an abstraction of "kekekeke," a bastardization of Japanese sounding laughter. See also keeklet.
