The lyrics go:
“Well, to be honest I’m a hetero guy
but I really try to be a good ally
and it ain’t no secret and I’ll tell you why
it’s cause I love my wife and my wife is bi
Bi wife energy, he has bi wife energy!
Now sometimes people assume I’m queer
and I have to say hey, just a straight guy here
and I get it a lot, I don’t mean to be cruel,
it’s just that my wife is a bisexual”
@Cringelizard’s original video received over 2.1 million views and he posted a second version of the song, which has been viewed over 500,000 times.
