1. A moment in a political speech, debate, film, or the viewing of an image that espouses the philosophy of liberty in a particularly kick-ass
way, so that it causes the recipient to experience any of the following: uncontrollable gleeful verbal outbursts, pumping fists, chills up and down back, warm fuzzy feelings, renewed vigor of political activism, bragging to other people around that they "just had a freegasm".
2. Intense emotional feeling comparable to a sexual orgasm, except it's not about sex, it's about liberty, so sometimes it's even better than getting your rocks off
"Whenever I checked RonPaulGraphs.com during one of the money bombs I had a small freegasm."
"When Ron Paul was schooling Mike Huckabee on foreign policy in that debate I had several freegasms in a row."
"Bill O'Reilly has never given anyone a freegasm. Ever."
