I thought you had multiple personalities?
So gubbe is singular? I'll have to remember that.
Though 'gubbar' sounds way funnier...., gubbe-gnoff!
Gubbe gubbe gubbar gubb...*chuckles*
En gubbe = One old man
Flera gubbar = several old men
When using "gubb" it's together with other words, such as
gubbhatt = old mans hat
If calling me an old man you's say:
gnoff är en gubbe!
gnoff is an old man!
