copy/paste from another site...makes sense thou...
the term comes from Victorian England. Remember that at that time folks would refer to women of questionable character as "blowsy?" (Think about literature you've read.) Well, "blow" was slang for ejaculate. So, getting a blow job meant creating an ejactuation in the man. Thus, "blow job" is from the masculine perspective of what happens to the man (rather than some odd, ineffective action on the part of the partner). Once again, the masculine bias reigns!
