Saying a person or entity "has some ‘splainin’ to do" (in a Cuban accent) is a humorous way of suggesting that they have done somethingillegal or otherwise embarrassing.
The catchphrase dates back to the 50's "I Love Lucy" show.
"Dude, asdfghjkl;!!!... why are my briefspink?? Lucy, you got some 'splainin' to do!"
When a roadman (preferably over lvl 203) says you have got some nice or “peng” shoes or “creps”
You (a new roadman lvl 1 with your mandem):Oi blud!
Little T(an experienced lvl 999 roadman with his mandem):Oi wagwan Mandem youve got some peng creps fam!
You:Thanks fam i be rocking these bare timbs!
