Saesaboo
A person who claims to be Welsh but obsesses over English Britishness, hates the Welsh Language but can barely speak English and also secretly hates the fact they were born in Wales. Starts anti-Welsh rants and comments with ''I'm a proud Welshman but....'', Facebook profile photo usually has a Union Jack frame. An Insult to true Cymry. Like a Weeaboo but with Saeson.
Saesaboo: The walsh azembly is uselss, the Welsh are too stupid to rule themselves, we are all British!, Plaid Cumree are a racist anti-British partee!
