look up any word, like tbt:
 
1.
A song (usually pop) that is so terrible, but catchy, that when it comes on the radio on a hot day, you have to roll up your windows so that nobody can hear you listening to it.
Rehana's Umbrella is such an AC song. It's so catchy, but I get strange looks when people see me singing to it from my car!
