1) Any term meaning a lot.
2) Term that back in the day, meant someone who worked for the betterment of the American condition. Liberals in these days were often very nice men who would donate a coin to the homeless child on the street who stole food on a nightly basis or the jack-in-the-box cranking monkey that banged a tin cup against the sidewalk while molesting innocent passerby.
3) Any inhuman, vile scum that merely acts for self-preservation and the ruining of others' fun. This list includes but is not limited to communists, fascists, illegal pieces of shit, spies, smart black people, hippies, stupid-as-fuck stoners that don't give a shit and associate with the cause because it sounds cool, revolutionaries, preachers, and people who think the missionary position is the coolest sex move ever invented.
Those fitting 3) want to see your fun ruined. They want to see Uncle Sam boning you in the ass, and they campaign for government healthcare so that the homeless people on the streets can rise up, steal your shit, overrun your cities and infrastructure, and ass rape your innocent wife and children, at your expense as well. They want to allow the frothing zoo of San Francisco to pollute the nation and turn the Stars and Stripes into Rainbowfest. They want a black president mainly so they can fulfill their misguided knowledge of racial equality and high five other liberal bitches on ruining the life of other, conservative, productive members of society.
1) I like my blowjobs with a liberal amount of slurping, please.
2) Did you just see that man help that poor Irish immigrant kid? He's so Liberal!
3) I was talking to Betty at the dinner party about stupid niggers in office, and it turns out she's a liberal! She's not getting the yearly Christmas fruitcake anymore.
