what does a circle with line through it mean
No symbol The international prohibition sign (official name), (also known as a no symbol, no sign, circle-backslash symbol, nay, interdictory circle, or universal no) is a red circle with a red diagonal line through it (running from top left to bottom right), completely enclosing a pictogram to indicate something is not permitted. The prohibition sign is sometimes seen in all-black, where color is not available.
Circle the Drain "Circle the Drain" is a rant song where, lyrically, Perry is telling off a self-destructive drug-addicted ex-boyfriend. Its candid lyrics[5][6] also discuss the strains his addiction put on both of them. In the track's chorus, she sings about how she wants to be his lover, not someone who has to take care of him, such as a maternal figure. She also sings about how he had ultimately lost large opportunities.[5] Styled in the genres of disco-rock,[7] and gothic rock tones,[8] it is an up-tempo song that lasts for four minutes and 32 seconds, and also has influences of techno.[5] The track is composed in the key of E♭ minor and is set in time signature of common time, with a tempo of 135 beats per minute. Perry's vocal range spans over an octave, from A♭3 to D♭5.[7][9]
