Well, this is awkward. 

Isla Fisher, Lizzy Caplan and Kirsten Dunst— stars of Bachelorette (due in theaters tomorrow, September 7)— made an appearance on Good Morning America, and while Fisher was telling a story about an incident with her mother and a male stripper, she made a sexual reference that left 50-year-old GMA host Elizabeth Vargas stumped.

"I went to the bathroom momentarily but then when I came back, a gentleman had removed his briefs," Fisher said. "[My mother] was on stage lying flat and he was about to tea-bag her."

The story would have been funny enough on its own, but Vargas wasn't even in on the joke.

"What's teabagging?" she asked.

"I'm not going to explain itit's her..." Dunst replied, before Fisher cut in and passed those duties to Caplan.

"Lizzy knows all about it," Fisher said.

But Dunst didn't even give her a chance to say anything. "You can google it later," she said.

We wonder if Vargas actually did.
