From Johnson’s Dictionary:

SLU’BBERDEGULLION. n.s. [I suppose a cant word without
Derivation.] A paltry, dirty, sorry wretch.
Quoth she, although thou hast deserv’d,
Base slubberdegullion, to be serv’d
As thou did’st vow to deal with me,
If thou had’st got the victory. Hudibras.
[Corrupted I believe from Scullion…a slovenlyscullion]

Seriously, who doesn’t love Hudibras?
