Using ones left hand to flitter and twiddle the external genitalia, or snatch of a clueless female who is trying unsuccessfully to be humorous or witty.

At the recent Texas vs. Nebraska college football game, a female Nebraska fan (Who thought she was being quite funny.) was seen wearing a shirt with the slogan: Callahan This. The shirt also had a large arrow pointing down to the minge.
“She thought she was being hilarious, so I Callahaned her.”

“When my girlfriend tells a bad joke, I laugh sarcastically really loud and then Callahan her cooter.”
