Full Mast

A complete and full erection of the male penis

As opposed to a "Half Mast" or "Semi" when the male is slightly aroused or drunk, and unable to achieve "Full Mast"

"Yasmine baulked as Franks Full mast loomed into view"

"Now at full mast , Greg was emabarsed and could not stand up to get off at his desired bus sop"

Janus ran full mast yesterday morning during his morning job through the nudist colony. He was running full mast, to the shock and envy of all.
