1) Word generators that give out gibberish(ish) stuff, and then come up with meanings for the words. http://klh.karinoyo.com/generate/words/http://bprhad.wz.cz/awkwords/index.phphttp://www.zompist.com/gen.htmlhttp://www.weirdhat.com/gibberish.php
A bunch I got from those with some übergüťťürääl szeťťýňğz to emulate the xübər-Türgıg bröğtəltý...
They're pretty lame, although consistent and alright for that purpose... well, let's simplify them to a more uniform and boring state and give them meanings based on what the first impression of them is; it's better to totally overdo the stuff at first in case you want to later do a sister conlang or whatever, or just want to change the stuff but have forgotten why you made the decisions you made in the first place.
tesijeg - a hand filled with water
bijoketfidi - a garbage dump
temukijodki - Genghis Khan's Swiss half-brother from the future
gekujubo - a person who wants to be a Japanese martial arts master but fails on every level
jehunget - Jehovah's witnesses who live a double life as gay porn stars
losegun - Han shot first
Well, those words aren't going to be very useful... so:
tesijeg - swimmer
bijoketfidi - garbage
temukijodki - memorable person
gekujubo - martial arts
jehunget - secret
losegun - war
There! Instant epic vocabulary!
2) Words from actual languages, "evolved"; eg. phonetic changes step by step. For example, let's use the Turkish word "kaplumbağa" (tortoise) and the Armenian word "yerjankutyun" (happiness) because they're pretty awesome words phonetically. First, let's mimic the natural evolution of words into separate directions, whatever sounds cool. Now we have "gəbrümbaqa" and "yerjəņütyün". All those sound changes make sense, so let's take it a step further while sticking to the exaggerated Turkic "gutturalisation" and adding a little bit of pseudo-Slavic squat warlord swag, leading to "cəbřümbaqa" and "jeřcəņğütjün". They might still be recognisable to some people, so one last step of phonetic and then aesthetic changes to make sure they're incomprehensible and brand new: "džäbřyňbör" and "žöřdžäňrytžyň". Voilà!I hope this is helpful, but if not, that's fine too.
