Teen Jesus and the Jean Teasers

The band was formed in July 2015 when all five band members – lead vocalist and bandleader Anna Ryan, lead guitarist Scarlett McKahey, drummer Neve van Boxsel, keyboardist Pip Gazard, and bassist Jaida Stephenson – were 15 year old students at the Orana Steiner School in Weston, a suburb of Canberra.

[10] On 6 February 2020, their fourth single "Desk Chair" was released, with Hayden Davies of music publication Pilerats praising it for being "gritty and rough-around-the-edges in the most charming of ways".

[8] The news was accompanied by the release's third and final single, "Girl Sports", which was described by Ellie Robinson from NME as a "notedly darker cut for the Canberra-native quartet" featuring "more grisly guitar runs, snappy, cymbal-heavy drums and cutthroat lead vocals".

[6] In August 2023, founding guitarist Scarlett McKahey announced that due to her struggles with postural orthostatic tachycardia syndrome, she would be unable to continue performing live shows with the band, but she would remain a member for recording.

[19] The band cites the Riot grrrl movement as well as the acts of Cherry Glazerr, Dream Wife, VOIID and WAAX as their biggest influences.

The band's lyricism has often alluded to events that have impacted their lives – "Girl Sports" is specifically written about a comment made by Stephenson's male dentist to "stick to girl sports",[16] and their debut EP's name is derived from remarks made by some listeners' surprise at the band's ability.
