Mark Pasc is running a neologism blog wittily (and neologistically) called neologasm. It consists entirely of sightings and definitions of newly-coined words. I found it because my recent Pika-pika entry was linked from his entry on Pika-pika. I liked thumbsuck (to pull data onto a thumbdrive illicitly) and lolmate (a friend with whom you share internet funnies).

Many of these are not meant to be taken seriously, they are more like sniglets, but in truth, who knows which might really catch on?
