When the sweat and smegma cause a man's peepee to stick to his scrotum.
Hey bruh, I had velcro dick so bad, I had to use both hands to peel it off my scrot to take a piss.
When a man has full balls but is only semi-erect, not quite ready for the big show. He usually requires a blowjob or handjob before he can insert his dick into her gaping hole.
I was watching this dude in the shower, and noticed he was starting to masturbate and was getting loaded up.
When a man is sexually aroused and has a chub, but not yet a full-blown erection.
Man, that guy is loaded up! Look at that thing! He is almost ready to go!
