It gets its name from the confectionary product
'Curly Whirly' and is when a male ejaculate
s upon a females/males arm when recieving
a hand job
. This is related back
to the 'Curly Whirly' as there are thin strands of excess chocolate on the product which
emulate the cum
on the females/males arm. The desired effect depends on how much you 'blast out of the cannon' and the proximity it lands over the arm of the recipiant.
