The term deceptive cadence is defined like this in Beatles song P.S. I Love You, where he writes:
"The second unusual type of progression is called a "deceptive cadence", characterized by the V (dominant) being followed by something other than the I chord. In the verse section, yet again, we find examples of the V being resolved in one case to the plain vi chord, and later on to the flat-VI. Aesthetically, it suggests a last minute retreat from coming to closure; a musical approach-avoidance."
P.S. I Love You is in the key of D. The song seems to prepare for an end by setting up a ii-V change (Bm - A), and you expect the tonic D as the next chord. But instead the song lands on the Bb chord, and goes in a chord stream Bb - C - D, or VIb - VIIb - I.
