Unpack Your Luggage
At the end of the night after all of your groping and fondling of a female to get laid has failed. In a last ditch effort you whip out your dong and let her know it's go time.
Man I was dry humping your sister last night for about 5 hours and she kept shutting me down so finally I just unpacked my luggage and next thing you know I was balls deep! When all else fails just Unpack Your Luggage.
