[R] Intersecting list vs rows in matrix

[GL]

Know that if I have List_1 and List_2 that I can check to see if the
intersect via the code below:

List _1: 
a, b, c, d, e, f, g 
List_2: 
z, y, x, w, v, u, b 
length(intersect(List_1, List_2)) > 0
return = true

If instead I wanted to check a dataframe that is a "list of lists," how
would I do that by record without looping?

List _1: 
a, b, c, d, e, f, g 

List_2: 
z, y, x, w, v, u, b 
y, z, w, v, v, u, m
z, y, x, a, b, c
.
.
.

return
true
false
true
