For non SAns: Tsek is what we say (t'sskec) when we want to tell something to fuck off; like a monkey or a bird or a person who is bugging you - tsek! and voetsek is the full version of that. Basically the Afrikaans for "bugger off"
The Afrikaaners are known for their "Great Trek" from the Cape to inland Johannesburg so it's a play on words as in refugees voestekking to America now, aka the Great Voetsek - the whole circle of Wagons etc.
AHAHAHAHAHA OMG Hilarious and we will crack jokes about ANYTHING. Comedy has always been a way we deal with serious issues - we can all laugh about it and deal with it. It's how we overcame Apartheid and racism too - humour, especially stereotypes and racial humour. In fact Nando's made an ad back in like 2011 related to this
