When playing an Online game, you have sudden bursts of lag, or are randomly disconnected. Usually when something awesome is about to happen, or when others are relying on you.
1. "Why didn't you heal the tanks?" - "Oh, I got comcasted."
2. "Sorry I shot you, I was being Comcasted."
3. "Why didn't you complete the mission?!" - "Meh, I got comcasted again."
To have one's Comcast cableinternet service suddenly cease working at the worst possible time. Unlike it's root word, castrate, comcastration can (and is, in fact, likely to) happen over and over and over to both men and women.
I was just about to pay my credit card bill online when I got comcastrated, causing me to miss the midnight deadline and incurring $28 in late fees.
Being stopped from doing something by an imposed limit, but not being told what that limit is under any circumstances.
If Disneyland was Comcasted:
Agent: "You have exceeded your fun limit for the day. You must leave the park immediately."
Tourist: "Limits? I wasn't told of any limits. What are the limits, if I may ask?"
Agent: "You may not."

To be randomly prevented from continuing your daily routine by people who do not care about their customers.
(When playing CoD4) To randomly start moving erratically as if you drank a cup of comcast's comcastic high speed, and see the infamous "connection interrupted" pop up.
