fisherman's tuck 

A way of concealing an erection by pulling the penis up and tucking it into the waistband of the trousers, then letting the shirt hang over the top to conceal the tip of the penis poking out above the trousers.

That guy over there just used the old fisherman's tuck to hide himself.
