qiǎle

Qiǎle (卡了) is a Mandarin slang which means that something lagged. Qiǎ (卡) means to lag, and le (了) is used after a verb to indicate perfective aspect (action completion).

It should be noted that 卡 is often mispronounced as "kǎ". In Mandarin, 卡 (kǎ) is used mainly for transcription, while 卡 (qiǎ) is used for native Mandarin words.
