Remove all lines beginning with words from another file

for wrd in `cat file2` ; do sed -i .bk "/^$wrd/d" file1; done
Given that file1 has bunch of lines (i.e. TSV file with first column as row titles), and file2 has bunch of words (i.e. row titles that are in file1), this command takes every word from file2, and removes every line in file1 that starts with that word.
