frig = 'to cheat'

[Jonathan Lighter]

Not in OED. So see HDAS; cf. syn. use of "fuck."

ca1840 _The Flash Minstrel!_ (London) [rpt. in Patrick Spedding, Paul Watt,
& Ed Cray, eds. _Bawdy Songbooks of the Romantic Period_ (London: Chatto,
2011) I 99:  D--n it, marm, you've frigg'd me out of my five bob!/ Tol de
rol &c.

And yes, there is a pun involved.

In the milieu of sub rosa, early Victorian bawdry, "damn" was too naughty
to print.
