What does gl ky mean in Tammy?

Gl is another name of "Lily", a concept in ACGN field, which refers to the pure love and admiration relationship between girls (that is, lesbians); KY refers to being out of date, for example, putting forward and sticking to an angle different from that of most family measuring bows and carrying a number of people with excess hair (a little unconventional, but the difference is that KY has no eye expression, which is similar to the passive formation without knowing)
