One of my Iranian colleagues back when I worked in an office had many entertaining phrases, like: "I go make some shoppings" "Time for go" Naturally, the rest of the gang picked them up and used them. I still say them to the consternation of others.
In a similar vein, "do the needful" has become so entrenched in some of my friends' vernacular that it's now used almost completely unironically. Also, "like such as," from the old "Miss Teen USA" viral video, has stuck in my craw to the point that its use is unconscious (though still intended humorously).
When I first started working I thought this was normal business speak. Thankfully my bosses noticed and when I told them it was definitely not spiteful or ironic, they tactfully educated me on the finer points of Indian phraseology.
