Here's a breakdown:

Kiki houses: These are surrogate families within the Kiki scene, providing a sense of belonging and support for youth, especially LGBTQ+ youth of color. They mirror the structure of traditional houses in the mainstream ballroom scene, with a "mother" or "father" figure leading the house and guiding its "children".

Get mama: In this context, "mama" likely refers to the Kiki house "mother," a seasoned and respected member who offers guidance, support, and mentorship. "Get mama" could imply seeking support or validation from the house mother, or achieving a level of performance or achievement that garners recognition and praise within the house and the wider Kiki community.

In essence, "Kiki house and get mama" highlights the role of the house mother in providing guidance and support within the Kiki ballroom scene, where young people find chosen families and develop their talents in a safe and empowering environment.
