Hahaha, not there's no joke.
Tied and soldered: a process where a wheel is built normally, and the spokes are tied together using wire, and soldered in place. When done properly it creates a "virtual hub flange" that is huge, making for a very stiff wheel. Can make it difficult to adjust the tension or true a rim though.
Sex lacing: rare and kinda strange, also known by many other names that I can't remember. Instead of the sets of spokes simply being crossed, they are actually twisted together multiple times, making a braid type arrangement. Very difficult to build well, but man do they look cool!
