Just my guess but I don't think this dude mentally handicap. he just obsessed and desperate as fu*k. He just wants a girl to talk to him so he gets on facebook on a pus*y hunt spree. He prob one of them dudes in highschool that all the girls consider to be nice but they just don't fu*k with him like that cause they think he crazy as fu*k. He don't get any attention so he begs bi*ches for time. Just one little call or text. I bet when dude just so happens to get a text from a girl, he goes all ape and sh*t. If he calms the fu*k down, he might by chance pull a chick.
Its only a matter of time before this boy ends up doing some fu*ked up sh*t to somebody cause hes been turned down. I get that vibe. Somebody need to set this muthafu*ka straight.
Like a comedian once said.
"I asked her for the pus*y. She said no, so I took it"
