Who's That What's That

"Who's That What's That" is a song by English YouTuber and rapper Niko B. It was released on 21 May 2020.

Composition
The lyrics features Bellic rapping about various references about every day teenage life in Britain. These include texting a girl on WhatsApp, buying a Big Mac and taking the gherkin out of the inside, buying vodka and going to a house party, losing his wallet, making profit on Bitcoin, a mad girl trying to fight his family and being late to school. She then burns down his house and once she has come to her house, he then leaves cocaine and alerts the authorities for her to be arrested.

The instrumental part consists of a repeated sequence of lofi rhode chords over a crackly vinyl sound effect, along with a simple drum pattern and a deep bassline. Bellic also provides various ad libs at the end of each line with added reverb. The song ends with a repetition of 'fuck gherkins'.
