Noun: Similar to an "Imperial Smackdown" or "mjolnir-slam", the swejhammer is a forceful and definitive heel-stomp on rabid ignorance or blatant stupidity, usually referring to logical debate. Wielders of the swejhammer are usually too cool to boast about their accomplishments, but may toss in a wry smile to accentuate a snarky remark, usually followed by a beer.
