Homo Slackass-Erectus....

They are referred to as “homo slackass-erectus” created by natural genetic downward evolution through constant spineless posturing and spasmodic upper limb gestures, which new research has shown to cause shorter legs and an inability to ambulate other than in an awkward shuffling gait.

The "drag-crotch" shape also seems to effect brain function. Expect no eye contact or intelligent verbal communication. History shows that this species mostly receives Job Seekers Allowance (although no jobs are sought) Housing Benefit and and full government care.

Unfortunately most are highly fertile.
