Buck Fifty 

An phrase coined by "TrainWreckTV" from Twitch.

It is an alternative for "I will keep it real with you".
TrainWreckTV (Tyler) is very candid with his viewers about his past and present, and he is not hiding things, and whenever he has a moment when he is going to tell something sensitive or very honest, he is saying "I will keep it buck fifty with you"

"I will keep it buck fifty with you, that new car that you bought is putrid"
"I will keep it buck fifty with you, I have some money problems"
