To turbocharge a girl, one must take a big breath of fresh air and blow it up her vagina to compress it (also known as supercharging). The compressed air will cause the girl to queef in your mouth. To turbocharge you must force the air from the queef back into the vagina and continue to eat the girl out.
My girlfriend asked me to turbocharge her while I was eating her out.
This is the practice of taking a hit off a joint holding the smoke in your mouth, then putting the joint ash side first into your mouth and blowing back the smoke through the joint into someone else'e mouth.
