Uvuvwevwevwe Onyetenyvwe Ugwemubwem Osas is a viral African guy who has a remarkable name. They say his name is the hardest name on Africa, although the pronunciation is pretty simple:

u-vu-vwe-vwe-vwe
o-nye-te-nye-vwe
ug-we-mu-bwem
o-sas,

but he said it very fast, although it's sure hard to spell.
