lamehaus
Somebody who used to be pretty cool, but is now ridiculously lame in every way possibly. Variations of the word keep the suffix "haus" but have a different prefix. Some variations include, but are not limited to: Highhaus, Faghaus, Rationhaus, Stealhaus, Liehaus, Foodhaus, Drivehaus, etc... Usually the prefix has a better ring when it is only one syllable, but in some instances (Rationhaus), it is acceptable.
Erik used to be pretty cool until he ditched us for that bitch Kati! What a lamehaus!
