With that nasty cough.
You know, the one you experience after all of your bong rips, because you smoke weed 25 hours a day.
There's a simple saying my grandmother always used to say:
SIP BEFORE YOU RIP.
I will work it out for you in a couple acts using GIFS, to help illustrate this lifesaving concept.
SIP
before you...
RIP
(we'll assume you're taking a rip at least 3x bigger than this elderly woman in the GIF did)
