That's when gay men, who aren't allowed to donate blood, bring straight friends to do so in their place. This is a move to call for the FDA to end the 1983 ban that prevents gay men from donating blood.
Volunteers say it's time for a change.
"It is our goal to increase awareness that this ban is no longer necessary. It was at the time, but because they test every blood sample for HIV and aids and other blood related diseases that it is no longer necessary how it is," said Scott Bogart, a volunteer.
People behind the gay blood drive are calling for Americans to sign a White House petition that calls for the ban to be lifted.
They need 100,000 names before it will be considered by President Obama.
