Chat roulette is not as successful as you think it is, and no - if you just say it to anyone on the streets, no one will understand what "chat roulette" is - it has a connotation of gambling or being very risky (ie the roulette thing billions of people understand conceptually, so your "analogy" will be hijacked)
Is it a platform for gambling in different languages? Is probably the response you'll get from "chat roulette for languages"
I'm going to disagree with you there. Occasionally I watch "old media" and for a while Chat Roulette dominated both traditional and comedy news shows as well as late night.
Many people on the street know exactly what it is: penises.
