According to the Austin Chronicle, the exchange occurred after the president asked Webb if he was gay while visiting a restaurant Thursday. When Obama went up to pay at Austin's famous Franklin Barbecue, the Chronicle reported that Webb, who was working the cash register, "threw his hand down and slapped the counter dramatically."
"Equal rights for gay people!" Webb declared.
"Are you gay?" asked Obama.
"Only when I have sex," Webb quipped.
Webb told the Chronicle the joke got Obama to laugh. He said the president told him to "bump me." The pair subsequently exchanged a fist bump that was captured on camera.
