throwing shoelaces 

To spew semen from your penis, can also be described as 'painting shoelaces'

'Bra, I painted a shoelace on that chicks face, y0!"
'I couldnt get no play from that chick, so I threw a few sholaces on my couch while watching some dirty monkey porn'
'Bros, I never met a chick that had me throwing shoelaces like I was on 3 Viagra's'
