What new dating fad involves dirty T-shirts?
Answer: pheromone parties
The up-and-coming dating method asks participants to bring a slept-in T-shirt to the party for others to smell. The idea is that party goers will choose a scent of someone they may be attracted to, according to USA Today.
Researchers have found that humans use scent as a method for weeding out genetic combinations that could lead to weaker offspring.
