Base 4.5 

Base 4 is just sex. Base 4.5 is also sex but with a little more interest. BDSM, Role play, Face Sitting, 69, e.c.t

Man, Ashley suggested we go to base 4.5 last night. I have been waiting for this for the whole 6 months we have been dating!

Base 2.5 

It refers to a point in the base system between 2nd base and 3rd base. It is dry-humping. It has always seemed more than simple groping but it is less than the handjobs/blowjobs of 3rd base. Dry-humping now has a definite place on the base system.

guy1: hey, y'know the base system?
guy2: yeah?
guy1: wher does dry-humping go?
guy2: base 2.5
guy1: ok cool thats good to know
guy3: you guys are fucking retarded

Base 2.5 

Base 2.5 uses powers of 2.5 for the numbers, it is considered binary and Base 5 at the same time.

Oh look! Base 2.5 isn't used! What a bad day!
