Running a tug boat means to have 3
men no more and no less than that, tugging one out (masturbating) in a horizontal line side by side all facing one
chick and blowing your
load all over her.
"Man that
chick is so
hot."
"Yeah she looks like she needs a good tug boat ran on her."
"Well boys hope you are ready to tug one out, let's
fuck up that pretty face of hers."
