A person who, after receiving a load of ejaculate on their body, does not clean the load off but rather lets it dry and walks around with it still on their body all day - hence "Hugging the Load" or a Load Hugger. Generally used colloquially to describe a rude or inconsiderate person - similar to douchbag.
What? Joe just put on his suit and when to work right after you spooged all over his chest? He's quite an enthusiastic load hugger, no?
More commonly: Chuck ate your last doughnut and left the empty box on your desk? What a load hugger.
