B: oh, you shake your damn head cuz studying's so stressful.
A: um, sure, lets go with that.
Example2: I got out of the shower at my girls house. She was watching american idol in the bedroom. So I stood in front of the tv, dropped my towel, smdh shakin my dickhead and broke out the helicopter on her.
'...everyone has their opinion i guess...smdh'. For further sublimation of said phrase, insert (shakin my damn head) right afterward so the noobs/trolls/oldfarts dont pry any further.
It's FUN to insult someone when only a select few understand the insult, but the moderators can't censor it without hesitation, if at all.
You: you obviously were dropped as a child, smdh. lulz.
You: smdh, you know you want to (shaking my damn head).
Dude 2-"Sigh...smDh at you."
