A standard BJ, only when the woman has an ice cube in her mouth so that your dick may be cooled and refreshed for further use.

Best used on extremely hot days after physical labor, when you have sustained an injury to your penis, or after intense sexual endeavors.
1) It was 98 degrees while I was mowing the lawn, so I had my woman cool me down with the old Mcgrath Air-Conditioner.
2) At baseball practice I got nailed in the dick by a baseball, it hurt so bad that the only cure was a good old Mcgrath Air-Conditioner.
3) We boned for like 8 hours, my dick was so sore that I absolutely needed a Mcgrath Air-Conditioner in order to not contract ED.
