Sag your trousers immediately you sight him, pull out your phone and start making fake call as you keep walking closer.
Talk loud like a street tout on the phone and start cursing whoever you’re supposedly speaking to. Change your walking step and bend sideways, and look unbothered. Be the first to greet him as he gets close, say “Boss, how far?”
Once he walks a few steps past you, quickly hang up the fake call and start singing into “Awon Goons Mi” by Olamide or any trench song at the top of your voice.
