The act of faking out girls by acting like you are attracted to men, only to lure them into a false sence of security and take advantage of them. Can be used as a noun (Look at GMT, what a prick.) Verb (He GMT'd that girl.)or Adj (Nice work GMT Man.)

Luring girls into a false sense of security by acting feminine around them. Then, when they least expect it, get them drunk and stick your penis in their herpee-riddled vagina.
Posto may have sex as a result of excessive gmt, but we got the last laugh, when his fresh case of herpees inflamed causing the itchiest crotch ever!
