A BDD is the opposite of a GDD (good dick day). This is a man's worse nightmare when he is thinking about pulling his manhood out in front of his friends or a girl. Guys can do an assessment of their dick by looking/grabbing shortly and can determine whether or not he is going to wish he never pulled his johnson out. But let's be honest, every guy has BDDs, we just try to limit the exposure of them so that our buddies don't think we have a micropenis! Causes of BDDs can include the cold, nervousness, post gym, just got out of the pool, being repulsed by a fat sow of a woman, or if you are just being a fucking cuck.
B- "Damn bro check this shit out, my dick is saggin' and looks good as fuck right now!"
K- "Wow! That is a nice, flaccid looking cock, man! I wish mine looked that big..."
B- "Ah don't say that man, we all have BDDs. It's all dependent on the kind of day you're having."
K- "Well I guess I've had a BDD for the past 8 months because my wife never wants to let me have sex with her. When I try to she just laughs and says 'Is it in yet?' Then she invites Michael over and he beats that shit up..."
B- "That's fucking why you cuck, you've turned yourself into a BDD having loser. LMAO"
K- "What causes BDDs bro? I need to have sex with my wife!"
B- "Well BDDs or bad dick days, is when your cock is not looking its finest and it looks like a Hershey kiss. They can be caused by a good pump from the gym, being cold, or in your case, just being a cuckboy beta male sissy dick."
K- "Do you want to fuck my wife?"
B- "Bro..."
