I asked my friend Jason about this one. Here is what he said:
"I think what she means is a blind straddle. What that means is the person who acts after the big blind makes a raise of two times the big blind, before looking at his or her hand. This is usually done to stimulate action at a table where the pots have been small with lots of pre-flop folding. Let’s say it’s a $6-$12 limit hold ‘em game, with the small blind $3 and the big blind $6. I am in the position next to the big blind and I straddle the pot by making it $12 before I look at my cards." — Jason
