Graduate went over and posted alternate meme showing negligent type of landlord, perhaps (8)
I believe the answer is:
absentee
'negligent type of landlord perhaps' is the definition.
I can't tell whether this definition defines the answer.
'graduate went over and posted alternate meme' is the wordplay.
'graduate' becomes 'BA' (someone with a Bachelor of Arts degree).
'went over' shows that the letters should be reversed in order (I've seen 'gone over' mean this).
'and' says to put letters next to each other.
'posted' becomes 'sent' ('send' can be a synonym of 'post').
'alternate meme' becomes 'ee' (I am not sure about this - if you are sure you should believe this answer much more).
'ba' backwards is 'ab'.
'ab'+'sent'+'ee'='ABSENTEE'
'showing' acts as a link.
Can you help me to learn more?
(Other definitions for absentee that I've seen before include "Someone not present" , "shirker?" , "skiver" , "are you fonder of him?" , "Deserter - truant b" .)
