There was a really cool Windows app about 10 years ago that helped you create names for just about anything: https://www.amazon.com/Summitsoft-00142-7-Name-Brand-Generat...

I entered “lisp compiler” and it offered me, among many others, “brainfuckteeth.com”. I can just imagine going to a VC with that proposed name. (It also offered “lisperl.com”, so I guess it knows that Lisp is a programming language.)

I found Namelix much better.

I got the catchy ae439fba780.com -- a snip at only £8.
