Generally [blank1]4[blank2] means you are whatever gender/sexual identity in blank1 searching for whatever identity in blank2 to have sex with. So like FM4F is a male/female couple looking for a female third and MtF4FtM would be a trans woman looking for a trans male.
Well, normally it means you are two males looking for two other males to have sex with.
Thank you
