It affects their blood circulation, I believe.
For one thing, the oxygen-carrying blood may find it difficult to get to the brain, thus causing the man in tight clothing to become stupid and irrational.

Really, Wong Tack needs to wear looser clothing....especially the pants.
For one thing, the impeded blood circulation clearly caused him to lose his mind quite a bit that he couldn't even acknowledge that those people he was scolding have a court order to clear the land.
This is very much like his anti-Lynas crusade of simply hantam to make people think he's a hero of some sort.
The guy also needs to know that such tight clothing is more for younger people. Old people like him shouldn't try too hard to look young with that kind of tight shirts and pants.
But then again, wearing tight clothing seems to be the trend among DAP men these days.

And Wong Tack's "I'm running the government today!!!" part is so typically DAPish.
These DAP men really need to loosen up a bit.
