Suddenly remembering with 思い出す

Takagi and Nishikata share an umbrella to walk home after school. Takagi says she completely forgot the term for two people sharing an umbrella. Nishika, with embarrassment, mutters that it’s あいあいがさ. When Takagi asks him to repeat it louder, he keeps quiet in his embarrassment.
